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.

* Make some LCD display related things globally accessible
* Deprecate `read_data` to avoid confusion (use `send_cmnd` instead)
* Allow arbitrary data for `send_msg` and `get_msg` (with optional parameter)

Only works in very new dev versions of Minetest; table font styling doesn't work at all yet, see minetest/minetest#10194.
Additionally, a little typo is fixed.
