Add default keymap for new black sundtek remote

this can be overridden by setting the keymap path as
system.hardware.sundtek.stick.<serial>.info.capabilities.rcmap 
also adding options to deactivate the receiver by setting 
system.hardware.sundtek.stick.<serial>.info.capabilities.remote_enabled to 0
and to set the IR protocol by setting
system.hardware.sundtek.stick.<serial>.info.capabilities.ir_protocol to the wanted string
