V0.3.2: Improved admin UI and performance galore

This commit fixes a plethora of bugs related to the admin UI, as well as
dramatically improving the performance of in-place editing. Furthermore,
several server bugs and misc bugs have been fixed. The admin UI is now
entirely client side when adding, deleting, or editng a category or
link. Other internal improvements hasve also been made.
