App does not work in iOS in Private Browsing Mode

Due to Mobile Safari's behavior in iOS5, any attempt to store a value to localStorage while in Private Browsing Mode will throw a QUOTA_EXCEEDED_ERR. TeamThing uses this API extensively and does not check to handle this error, thus breaking the app on load.

TeamThing should A) handle the error better, and B) look for a work around to avoid this problem in Private Browsing Mode.
