RE-enable Sense

WARNING: this does not work perfectly for everyone!! some have it working with no issues and some dont. it works fine for me but may not for you! a full backup of your phone is HIGHLY recommended before installing just in case. if you do have issues try to report them with as much details as possible so we can get them fixed, thanx!
