Imported some of the GPLv3'd changes from RhodeCode v2.2.5.

This imports changes between changesets 21af6c4eab3d and 6177597791c2 in
RhodeCode's original repository, including only changes to Python files and HTML.

RhodeCode clearly licensed its changes to these files under GPLv3
in their /LICENSE file, which states the following:
The Python code and integrated HTML are licensed under the GPLv3 license.

(See:
https://code.rhodecode.com/rhodecode/files/v2.2.5/LICENSE
or

for an online copy of that LICENSE file)

Conservancy reviewed these changes and confirmed that they can be licensed as
a whole to the Kallithea project under GPLv3-only.

While some of the contents committed herein are clearly licensed
GPLv3-or-later, on the whole we must assume the are GPLv3-only, since the
statement above from RhodeCode indicates that they intend GPLv3-only as their
license, per GPLv3§14 and other relevant sections of GPLv3.

Make the private icon of repo more distinguished from
the public one. Makes it easy to see which repositories are private.

Removed shortlog aka lightweight changelog.
Current version of changelog is fast and condensed.
There's no sense to keep changelog duplicity.

swap repo-size with settings in summary. It somehow
feels more natural to be on bottom, it's just easier to click

summary: redirect from repo URLs with #branchname to changelog with this branch

This implements partial support for the Mercurial syntax for specifying
revisions so https://secure.rhodecode.org/rhodecode/#beta works both for
pulling with Mercurial and browsing.

This uses javascript, and has a bit of extra support for onhashchange in HTML5 browsers.

#749 and #516 Removed dupliciting of repo settings for rhodecode admins and repo admins
- repo admin now is allowed the same set of operations as the rhodecode admin
- single logic for forms/validations/permissions
- fixes #805 update external repo via webinterface
-

follow Python conventions for boolean values

True and False might be singletons and the "default" values for "boolean"
expressions, but "all" values in Python has a boolean value and should be
evaluated as such. Checking with 'is True' and 'is False' is thus confusing,
error prone and unnessarily complex.

If we anywhere rely and nullable boolean fields from the database layer and
don't want the null value to be treated as False then we should check
explicitly for null with 'is None'.

improved title consistency
- changed - into dots to save space

small UI changes for dropdowns on upper menu
and summary boxes

Fixing missing icons.
Removing the breadcrumb from the box header, so it will only be on the context bar.

Addding context bar to more repo related pages.
Fixing the base template to work on non-repo related pages.

Adding the context bar too all pages related to a Repository.
Deleted top menu items that are on the context bar already.

don't show rss links - atom is the present and the future

- following the reasoning on http://selenic.com/pipermail/mercurial-devel/2012-December/046542.html

summary: show "Show by ID" toggler after the clone url

It looked like something important ... but most users don't need it.

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

merged + fixed pull request #62: Implemented metatags and visualisation options.

given revision, rather than tip

Added h.tooltip to all places that tooltip_title is used.

default utf8 to some other encoding.
- also added instance-id to config
- update ini files

fixed percentage in stats
fixed menu css

fixes issue #271
- OrderedDict serialization sometimes failed due to how odict is implemented. Dropped usage of it for a simple tuple

- fixes celery sqlalchemy session issues for async forking
- summary page css fixes
- speed optimizations

unified generation of repo groups choices
added on-the-fly conversion to new repository groups format (supporting path as a link)

fixed issue #165 trending source files are now stored in cache as ext only, and translated to description only when displaying, so future changes of mappings will take affect right away.
Also changes the way how map is generating, ie. autogenerate from pygments lexers, and than complete with user defined mappings.

#109, added optional clone uri when creating repo.
Cleaned up repos controller moved common code into __load_data
