Added fixed lingering text after making post

For now, the fix is more of a hack. $route.reload() is called after a
post is successful to clear out the data in the directive but the true
fix for this would require updating the directive to two-way bind to the
parent's scope vars.
Added ngAnimation

Added the ngAnimation module to add a fast fade-in animation to most
page changes.
Removed moderators

Removed all html that had any mention of moderators from the code.
