* Removed the deprecated MyAvatar.setToggleHips script function and the "Toggle Hips Following" option from the Developer menu. They had no effect on any code.
* In CharacterController::applyMotor, prevented unnecessary calls to btVector3::rotate() when the motor has no rotation. This change also improves readability through the use of clearly-named lambdas.
* In AvatarData::getFauxJointIndex, prevented unnecessary string comparisons when the named joint is a real joint rather than a faux one.
* In Avatar::getJointIndex, removed an unnecessary call to QHash<QString, int>::contains(), by supplying a default index for QHash<QString, int>::value().
* Removed unnecessary condition "forwardLeanAmount < 0" in MyAvatar::FollowHelper::shouldActivateHorizontal_userSitting.
* Corrected the return type of MyAvatar::getSitStandStateChange from float to bool.
* Added a missing 'f' suffix to a float literal in PreferencesDialog.cpp.
