Set the cookie path to be SITE_ROOT.

The cookie path was being set to SITE_ROOT, but too soon, before
SITE_ROOT was set in settings_local. Now it's set after we've loaded
settingS_local.
Fix the PYTHONPATH issue for good (hopefully).

The latest change to set PYTHONPATH to be limited to the location of the
settings_local.py file broke virtualenvs, which no longer set PYTHONPATH
correctly and break rbssh.

PYTHONPATH seems to be a complicated beast when virtualenvs and
pkg_resources comes in, so we're just going to stop dealing with it
here. Instead, we're using a new variable, RBSITE_PYTHONPATH, which will
point to any paths we have within a site that we care about. For now,
this is the conf/ directory. rbssh will specifically look for this and
add the values to sys.path.
Allow specifying the MySQL port in rb-site.

When configuring a site using 'rb-site install', the hostname of a MySQL
database can be specified in hostname:port format. This works for the
wizard and for the --db-port option.

Release Review Board 1.7.7.
Fixed the default for the web server port in rb-site.

The default was an integer, which broke generation of some files. It's
now a string, like all other parameters.
Move the Review Board release notes directory up a level.

This was done previously on master, but it looks like the moved file
info wasn't tracked by git. That made updating release notes on 1.7 and
merging painful.

This attempts to fix the situation by redoing the merge on 1.7.x. Master
will then be fixed appropriately.
Release Review Board 1.7.7.1.
Require Django Evolution 0.6.9 or higher.

0.6.9 fixes some significant issues some people have hit when upgrading
old installations. It's better at handling larger upgrades where new
models may be created and then change in evolution files.
Enable logging of request info for Review Board.

This improves Review Board's logging to use Djblets's new request
logging code. This will log the localsite name (if any), the username,
and the path of the request.
