Remove Request::set_user_agent() in gallery_unittest since Request::$user_agent is public.
- remove Request override class.
- change comment and akismet tests to modify Request::$user_agent directly.
- add more comprehensive setup/teardown for akismet test.
Change error reporting in Controller_Gallery_Unittest back to -1 from E_ALL | E_STRICT.
Also, add a note to keep people like me from unnecessarily doing this again...
