Add support for reading distributor slot status. This action is complementary to already present filter setting function. 'port' distributor message is modified to accept filter color only (without '=on/off'), device returns selected filter state. A wrapper function ($get_filter(...)) for Lua Controller and condition selector for ICTA Controller are implemented as well. Signed-off-by: Michal Cieslakiewicz <michal.cieslakiewicz@wp.pl>
