Added tests for creating/removing a menuitem for the purposes of the sideblock tests, and made the test suite use it. Passes fine on trunk right now.

Have a read of the README for more information. In a nutshell, you can now make
your own test suites for Mahara, there is an organised structure for this.
There's still some work to do, but so far the foundations are good.

Some moving around of test stuff, attempting to create a standard structure for testing. Beginnings of a script for generating test suite files for tests

Fixed bug #712 - now 'site default' is allowed as a language setting for people. Newly registered users have this default, so if the site language is something else, they will be using that by default.

Added check that HTTP_USER_AGENT is available when doing an MSIE check. An error in the logs alerted me to this.

Fixed bug where finding search results + querying for an offset that doesn't contain any of the results was causing an error.

We shouldn't trust $results['count'] being > 0 to mean that $results['data'] has anything in it.

Bug tracked down from an error in the logs on production.

Renamed 'recent activity' to notifications. It's a bit of a 'dumb' rename, not taking filesystem paths or grammar into account, but then the whole settings section needs a path overhaul later anyway.

Fixed bug #1120 - broken language string when attempting to register with invalid password. Thanks to Aaron.

Fix bug #923, missed converting a 'c' table alias to 'g' for the communities -> groups transition. Good catch by Heinz

Fix for bug #726, another string made translatable. While I was there I json_encoded some of those get_string wotsits.

New js language file for german from Heinz. git diff isn't telling me what exactly the difference is tho...
