lok: add rendering and input for form controls in Calc

Until now the form controls were nto rendered to a tile when
drawing tiles for LOKit usage (online). This change adds
LokControlHandler that is responsible for rendering of the
form controls on the tiles (currently implemented only for Calc)
and handles mouse input events that come through LOKit.
