This PR:
- Refactors the doctrine class to have a bit more structure, in
anticipation of adding more elements to Doctrine.
- Moves previously hard coded helo-specific altitudes into the Doctrine
class, aligning a bunch of altitudes ~200ft in the process.
- Refactors ingress_altitude to combat_altitude to clarify that the
altitude is applied to multiple waypoint types, not just the ingress
altitude.
This PR refactors the Doctrine class to load from YAML files in the
resources folder instead of being hardcoded as a step towards making
doctrines moddable (Issue #829).
I haven't added anything to the changelog as a couple of things should
get cleaned up first:
- As far as I can tell, the flags in the Doctrine class (cap, cas, sead
etc.) aren't used anywhere. Need to test further, and if they're truly
not used, will remove them.
- Probably need to update the Wiki
