Control radio/TACAN allocation, set flight radios.

Add central registries for allocating TACAN/radio channels to the
Operation. These ensure that each channel is allocated uniquely, and
removes the caller's need to think about which frequency to use.

The registry allocates frequencies based on the radio it is given,
which ensures that the allocated frequency will be compatible with the
radio that needs it. A mapping from aircraft to the radio used by that
aircraft for intra-flight comms (i.e. the F-16 uses the AN/ARC-222)
exists for creating infra-flight channels appropriate for the
aircraft. Inter-flight channels are allocated by a generic UHF radio.

I've moved the inter-flight radio channels from the VHF to UHF range,
since that's the most easily allocated band, and inter-flight will be
in the highest demand.

Intra-flight radios are now generally not shared. For aircraft where
the radio type is not known we will still fall back to the shared
channel, but that will stop being the case as we gain more data.

Tankers have been moved to the Y TACAN band. Not completely needed,
but seems typical for most missions and deconflicts the tankers from
any unknown airfields (which always use the X band in DCS).
