Add persistence of active gestures. This needs an UGAIM update to work.

Active gestures are sent as part of the login-response. Added
fetchActiveGestures to SQLite and MySQL; added an empty one for MSSQL and
NHibernate. Using the empty ones won't cause errors, but doesn't provide
persistence either, of course.
