Telemetry control via IIDK

Telemetry is controlled via IIDK using simple reactions described in the TELEMETRY section of Programming guide, for instance:

CORE||DO_REACT|source_type<TELEMETRY>,source_id<1.1>,action<LEFT>,params<1>,param0_name<tel_prior>,param0_val<3> – message sent to port 1030 in order to rotate camera lens left with high priority.

TELEMETRY|1.1|LEFT|speed<2>,tel_prior<3> – reaction to port 1030 in order to rotate camera lens left with high priority at an average speed.
