- The SA-8 LD unit hat the SA-13 unit name as variant. The Layout tried to create a SA-13 SHORAD Site but actually used an SA-8 LD unit instead with zero threat range. This resulted in a yellow marked GroundObject on the map
- Cleaned up the treat and radar range functions a bit
- completly refactored the way TGO handles groups and replaced the usage of the pydcs ground groups (vehicle, ship, static) with an own Group and Unit class.
- this allows us to only take care of dcs group generation during miz generation, where it should have always been.
- We can now have any type of unit (even statics) in the same logic ground group we handle in liberation. this is independent from the dcs group handling. the dcs group will only be genarted when takeoff is pressed.
- Refactored the unitmap and the scenery object handling to adopt to changes that now TGOs can hold all Units we want.
- Cleaned up many many many lines of uneeded hacks to build stuff around dcs groups.
- Removed IDs for TGOs as the names we generate are unique and for liberation to work we need no ids. Unique IDs for dcs will be generated for the units and groups only.
A possible explanation for the infrequent CTDs we've been seeing since
adding fast forward is that QWebChannel doesn't keep a reference to the
python objects that it passes to js, so if the object is GC'd before the
front end is done with it, it crashes.
We don't really like QWebChannel anyway, so this begins replacing that
with FastAPI.
