SQLiteDatabase/changedRowCount: maybe we can use "select changes()" to get the count of changed rows

Thanks for your great job.

I've recently found the CHANGES() pragma available inside of SQLite. So I'm adding some code:

SQLiteStatement stmt = sqliteDatabase.compileStatement("SELECT CHANGES()");
long cnt = stmt.simpleQueryForLong();
stmt.close();
return (int)cnt;

:D

Thanks. Fixed with #65.
