Upgrade jquery.cookie to 1.4.1.

This is because of Bug 3387 where if any cookie exists on the domain that has
an invalid URL escaping, for example, a cookie like 'foo=%%', then the entire
site will roughly stop working. This was fixed upstream in jquery.cookie
between 1.3.1 and 1.4.1.

This can be verified by running the live 2.0.1 on a machine, and running the
following on a JS console:

```javascript
document.cookie = 'foo=%%';
```

and then refreshing the page. it will stop working; if you try to view a diff,
the parts will not load but will spin forever. This seems to be because the JS
fails to load. After applying this diff it will start working :). This
situation can occur if reviewboard is run on a subdomain like `rb.example.com`
and there are cookies on `example.com` that contain this kind of string. This
is a regression from 1.7

Testing Done:
Played around with the site and didn't see anything wrong. More testing would
be appreciated as this is my first review posted and whatnot. I'm just going to
roll this out internally to our site though and hope for the best :)

Merge branch 'release-2.0.x'
Change the API for get_remote_repositories().

get_remote_repositories()'s API was using plan IDs as a way of
identifying users vs. organizations, which led to some redundancy.
For example, "private" and "public" for GitHub meant the same thing
(users). GitHub in particular was assuming certain filter types for
repositories, which would be handy to specify from a caller's point of
view.

The function has now been changed to remove the plan parameter and to
instead have a dedicated "owner_type" parameter that specifies what
"owner" refers to. The value is dependent on the hosting service, and
HostingService subclasses are expected to be smart about the defaults.

It also now takes a "filter_type" parameter that allows for filtering
repositories. Possible values are dependent on the hosting service as
well. For instance, GitHub's allowed values consist of what their API
natively allows for their "type=" parameter in repository queries.
