A quick couple of bugfixes to solve an ongoing problem at $work. It turns out that using the plain app as the index app was contingent on the filesystem's ordering or some other unpredictable thing. Now, this is fixed, so the plain app can be safely used as the index.
This will be fixed/changed completely to allow any page to be the index in a future version.
Additionally, some footer styles were added to the default theme.
