fixes issues #849 IMC failed for non-ascii files

- added set of regression tests into vcs lib

Implements #842 RhodeCode version disclosure.

- it's now implemented as visual option in settings

Add default for dashbord items and create default
settings in a sane way.

Changed default behaviour of dbmanage to fix issues with continues
migrations from multiple versions

Switch gravatar to always use ssl.

- there's no reason why not to.
- removed thread locals imports thanks to that
- use internal RhodeCode config for alternative gravatar url

Added use_poll option for latest waitress release.
If fixes issues with 1024 fd limit.

- added example of gunicorn config. It includes
a note about not using multiworker setup.

Fixed issues with group renames for local repository group admins.

- revoke permission on yourself check was triggered thus preventing
group update. Moved this check into update permission function

Explicitly tell fileinput that we use '-' as read source

- minor docs improvements

Fake post-push actions when doing git fetch. It's still want show
what revisions we fetched but at least we trigger the action

Added --format into gist CLI

- default --pretty format will give a nice message about gist creation
- api_call shouldn't do any printing let the CLI decide about that
- return pure json with --json format

refactored url.resource to full definition of routes

- id -> gist_id

show admin menu and list for users who are admins of repos.

- this is consistent with user groups, repo groups displaying.
- fixes 403s after you actually delete a repository being it's admin

Do read only checks on attach as fork of repo list.
We shouldn't leak repo names here to which we don't
have access

Repository groups: super admin shouldn't have the permission set
when he creates a group. Super admins anyway can edit groups even without
explicit permissions set

added alias configuration option for gists.
Used to generate nice looking urls for gists

Prefix gist storage with rc, and store some metadata info into
gist store repos

Implemented simple gist functionality ref #530.

- creation of public/private gists with given lifetime
- rhodecode-gist CLI for quick gist creation

fixed issue with web-editor that didn't preserve executable bit
after editing files

fixed issue with web-editor that didn't preserve executable bit
after editing files

vcs: fixed issues with calling get_changesets method doesn't
throws EmptyRepositoryError when called on empty repos

api: decouple some parts from api CLI script
- also change how we save config file
- method should be always API method
- now we use --save-config for saving api config

Use repo-scann at latest possible state.

- we can ensure every config/checks were made before that step
- it should fix issues with custom GIT paths

created basic TestClass for tests that does
basic pylons stack init

moved top-level tests to rhodecode/tests/other.

- There are no toplevel tests
- moved proper files to fixtures where they should be in the first place

removed duplicate code that set os.environ['RC_SCM_DATA']
this was done via __inject_extras anyway

diff parser: redefined operations stats for changes

- don't loose info about multiple operations like rename + chmod
- new Binary flag when dealing with binary file operations
- fixed diffs after mercurial 2.6 when GIT binary diffs were fixed
- added more tests for multiple operations

- refactored the way diffprocessor returns data. It's
now easier to extract type of operation on binary files
- diffprocessor doesn't append that information into the diff itself

diff parser: prefer git headers over old unified diff headers

Makes the diff show both rename and chmod info and the diff.

diff parser: more correct detection and reporting of binary git diffs

git mode is not just used for binary diffs.

diff parser: match the header order of hg diff --git patches

The output might look like:

diff --git a/A b/B
old mode 100644
new mode 100755
rename from A
rename to B
--- a/A
+++ b/B

Such files were shown as 'modified binary file chmod 100644 => 100755' without
diff.

Now the chmod and diff will be shown ... but still not the rename.

Correct parsing of headers do require a better parser - one do not just use a
regexp.

diff: don't link to removed files

It is 'D' for removed, not 'removed'.
