Ticket 136: window.openDatabase() in Android 3.0 throws SECURITY_ERR (most code written by Simon MacDonald - I just tested and checked in)

Browse Source 
When you call window.openDatabase() on an Android 3.0 device you get and error something like this:

E/Web Console( 1791): SECURITY_ERR: DOM Exception 18: An attempt was made to break through the security policy of the user agent.

Simon worked with Pat for a bit and they think this is a WebKit or Android/WebKit interaction bug. In the meantime this fix determines if you are on Android 3.0 and uses Droid_DB if so.
