Cap rework (#48)

- Refactored all CAP classes.
- Improved timing
- Zones are now not tied to MissionStages
  - CAPROUTE_<routeID>_<free>
  - routeID is now what is used in the naming convention.
- Units taxi back to their spawn parking space and rearm there.
  (Units destroyed while in the Rearming or Repairing state are not taken into account)
