Implemented #532.
- now displaying username + full name for mapped users from RhodeCode

Implemented basic locking functionality.

- Reimplemented how githooks behave
- emaulate pre-receive hook
- install missing git hooks if they aren't already in repo

fixes issue #531, when extracting user email, we check it against the database,
and return user default email. Also if no email is present check the username
for matching targets.

added highlight lines field in ChangesetComments, will be used
later for attaching comments to blocks

fixed missing div on my_account + added nothing here yet when there are no
pull requests for user

Load generated revs while switching to other sources of pull-requests.
Issue before was that extra tags or bookmarks weren't present in the dropdown

Changed v.Set validation into our own that actually raises exceptions on missing values.
Added NotReviewedRevisions validator

fixes issue #524
- fixed search by filename
- added missing test for this search

Added optional flag to make_ui to not clean sqlalchemy Session.
Don't clear sqlalchemy session when using make_ui in admin repo form

use os.environ as a fallback for getting special info from hooks, this will allow
calling RhodeCode hooks from outside the system eg. via SSH
- also verify repo if it's a correct VCS throw 404 error otherwise

new summary for opened pull requests
ref #523

added more validations when opening pull request
- fixed issues with moving tags/bookmarks/branches after opened pull-request
- no longer possible to open a pull-request without changesets
- title is required
- validate reviewers and revisions

RhodeCode now has a option to explicitly set forking permissions. ref #508
- changed the way permissons on users groups behave. Now explicit set on user
is more important than permission set on users group

Added form for controlling mercurial extensions
added hggit also for future

Fixed validators for remote repos
- use proper httppeer repo for mercurial 2.3
- validate git repos for remote auth
- docs updates

allow cloning with hgsubversion (reimplementing pull request 46)

sadly I get a exception from hg-git when doing the same for git+http URLs
so I did not implement it for hg-git

switched repo_name to non greedy match.
In some cases greedy match can confuse routes system, and return 404 for valid urls

fixed issues with non-ascii chars in new file browser
- patches history.js to handle non-ascii urls properly
- wrap c.file.path into unicode for mako

fixed the push_ssl issues after mercurial 2.3 upgrade.
Set always to false, since rhodecode handles that by dedicated middleware.

Disable the html4 history mock for old browsers.
Enable search filter on initial page load

Reimplemented file-browser using partial-ajax
- improves the speed of browsing of files for revision
- url push state via html5 History
- also cache the results of calls for even faster handling the content

Bumped mercurial version to 2.3
- fixed issues with compare of two remote repos at particular revisions
- added tests for cases when mercurial update broke code and tests didn't catch this
- removed obsolete EmptyChangeset from the rhodecode code

add option to disable whoosh index in tests via an enviroment variable.
- helps speed up testing, when whoosh is noot needed

add example when having chunking module for nginx enabled.
- overcomes large git push issues and having to set postBuffer in gitconfig

removed ftp from allowed schemas
- added tests for the schemas fix
- moved parsing url if we only have came_from present

security fix, inspired by django security
announcement: https://www.djangoproject.com/weblog/2012/jul/30/security-releases-issued/
- filter out bad schemes and netloc differences

Forbid changing changset status when it is associated with a closed pull request
- fixed some issues with cascade deleting repos with changeset statuses attached

merged + fixed pull request #62: Implemented metatags and visualisation options.
- new tag lang
- fixed found issues
- added simple test

Implementes #509 require SSL flag now works for both git and mercurial.
- check is done at earlies possible stage
- if detected protocol is not https and flag require is there RhodeCode will
return HTTP Error 406: Not Acceptable, before even checking credentials
- removed push_ssl flag from mercurial UI objects since that would duplicate logic

cascade fixes for comments/pull-requests/reviewers
when deleting a repo. Just CLEAN ALL !

rewrote admin repos page.
- less info (no VCS data), but much faster.
- having 1000s of repos is not a problem now
- pagination/filtering using YUI datatable

No more raw html inside users controller.
We use cool mako Template features

sqlalchemy sessions cleanup in admin
Cleanup settings options

implemented admin panel Users table with YUI datatable
- much better handling of big amount of users
- filtering by username
- sorting by columns

Refactored create fork function to use new RepoModel functions instead of old
soon-to-be-destroyed functions

little code cleanup
- added some additional logging

fixed tests for search
- was written for just mercurial repo without having git

when indexing changesets use the raw_id to locate the point from
which to start indexing rather than the revision which can be unreliable.

Reverted delete zombie repos on server start, this can be misleading, and somehow dangerous option.
It's better that server restarts as fast as possible without any magical functions going on. Cleanup can be still made from rescan option in admin

Deprecated validation of operating system, we just care if it's windows, let approve all other
systems.
- help to supports cases like cygwin etc
- fixed typo in auth decorator
