Merge commit :(. Bring in my work on URLs and UITabBarController into one functioning...

 - Queueing badges and controllers work.
 - As far as I can tell, no broken URLs on Cydia pages.
   - There might still be one the website, but that's not under my control.
 - Lazy loads tabs again, but also doesn't reload the home page when switching back to it (yay!).
 - Adds "Show Pacakge Settings" duplicated text as a section header on the PackageSettingsController, for asthetic reasons.
 - Popups are *still* broken, and I still don't know why.
