Loadout implementation cleanup.

Loadout selection no longer has two (disagreeing) implementations. What
the UI shows is now what the miz will have.

We now store the chosen layout in the Flight *always*, not just for
custom loadouts. This means that we do loadout lookups at the start of
each turn, but the data is cached in pydcs.

Era-specific loadout degradation is still done at generation (and
presentation) time. This is so that players can toggle that option and
have it affect the *current* turn, rather than the next one.

-This is a list of mappings from the FlightType of a Flight to the type of payload defined in the
-resources/payloads/UNIT_TYPE.lua file. A Flight has no concept of a PyDCS task, so COMMON_OVERRIDE cannot be
-used here. This is used in the payload editor, for setting the default loadout of an object.
-The left element is the FlightType name, and the right element is a tuple containing what is used in the lua file.
-Some aircraft differ from the standard loadout names, so those have been included here too.
-The priority goes from first to last - the first element in the tuple will be tried first, then the second, etc.
