Added all of the app graphics for all devices. (App icon, launch screen, spotlight icon.)
Syncing local and remote repository, because I can't push until I do.
Added glyphicons and DisclosureIndicator to the home page. Removed HomeViewController because it wasn't doing anything, and the home TableView doesn't need it.
Added staff model objects and functionality. Added and configured TFHpple for downloading and parsing HTML. When the app starts, the staff table is downloaded and parsed. The staff are displayed correctly in the staff directory table view, but nothing happens yet when you tap a member. Added scaffold for more teacher information.
Finished caching and download checks for the staff directory. The staff directory is only downloaded after 6 months, January 1st has been passed and the cache is old, or the set re-download date has been passed and the cache is older. Also improved some variable names and functions to be more descriptive/have less code.
