This can increase performance for huge repositories like 300K changesets

Basic implementation of cherry picking changesets
for pull request, ref #575

Fixed issue with inproper handling of diff parsing that could lead to infinit loops.
This was an edge case when diff contained diff data inside. Regresion test was
added

implements #649 added two seperate method for author and commiter to VCS changeset class
- switch author for git backed to be the real author not commiter

implements #636, lazy loading of history and authors to speed up page responsiveness.
- loading full history is not always needed, and it's very heavy operation. Now this is lazy loaded
when clicking on button

- journal will now display nicer labels for create tag, and delete branch operations for git

new patch function, and urls schema.
now rhodecode generates
- diff
- plain diff
- patch files

both for git and hg

on whole diff instead of per file diff. That
can give a big speed improvement for large changesets in
repositories with large history.

- show renames of binary files
- implemented new diff limit functionality
- unify diff generation between hg and git
- Added binary indicators for changed files,
- added diff lib tests

small anchor cleanup
- fixed readme positioning with fixed bar
- added anchor link to inline comment

fix for issue #602, enforce str when setting mercurial UI object. When this is used together with mercurial internal translation system
it can lead to UnicodeDecodeErrors

Let the function calculating changeset history do all the work
- fixed exception handling for fallback method

implements #632,
- added branch/tag/bookmarks info into feeds
- added changeset link to body of message

added/changed/removed methods didn't use generator methods to return the list of changes
- added test for that case

fixes #612 Double quotes to Single quotes result in 4; to 9; in a visual Diff. Markupsafe.escape method usage
was causing some unpredictable behavior

deleting a group now does same archive operation like deleting repositories. Improve prompt that show number of repos that will
be archived together with a group.

don't check for url issue links, since we always want to linkify changeset into a repo link, fixes issue
with issue_pat beeing disabled breaks the urlification

Update last_change from VCS data on request.
- lightweight dashboard shows now last_date also taken from db and it is fast !
