* Adjust white space and quoting.
* Bumped version to 1.0.0.RC8
* Use a single SQLiteDatabase object for all connections to the same database.  This utilizes the Android SQLite locking mechanisms which are better than ours.  We still need the timeout/retry feature if the database is accessed from multiple processes.
* Added a retry interval parameter to the URL.
* Pulled logging into separate class to configure log level ans ensure unified log tag.
* Added some logging to track threads and locking.
