First step in two-part process to rename directories to kallithea.
This first step is to change all references in the files where they refer
to the old directory name.

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
http://web.archive.org/web/20140512193334/https://code.rhodecode.com/rhodecode/files/f3b123159901f15426d18e3dc395e8369f70ebe0/LICENSE
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.

Added pre-create user hook.
It allows to control user creation using rcext hooks.

Allow RhodeCode maintainers to specify a custom bug tracker.

This allows people who maintain large RhodeCode installations to setup their
own bug tracker and respond to requests against their specific installation.
The maintainer is then free to forward problems with RhodeCode to the
canonical issue tracker on bitbucket.

If the config option "bugtracker" is present, its value will be used with the
"Report a bug" button. If left blank, this disables the button. If no value is
present, then the default is used. This is so that the new config option
doesn't break installations of RhodeCode upgrading to a newer version and to
allow easier installation for the common use case.

Added flag to controll option for changing the repos path location
from web interface

Implements #842 RhodeCode version disclosure.

- it's now implemented as visual option in settings

Wrapped calls for git and hg middleware in extra block that clears db Session.
tries to fix #318

commit less models

Fixes issue #201
Fixed bug when repository was deleted on filesystem, and not from rhodecode
