Weapon Firing Arcs for Space Showdowns

- Weapon Firing Arcs limit what directions a weapon can fire in.
- Ships have direction and require a new turning step to travel.
- These rules only apply to capital ships or larger, and currently only in showdowns.
- Weapon Arcs will need to be configured on ships within the showdown configuration.
- The rules are available here.

Changes

- Droid repair now searches within containers and within the room to find accessible droid parts.
- A character leaving a faction will no longer send leave events to subfactions the character was not a member of.
- Fixed an issue where ships within hyperspace abort cooldown would be invulnerable in combat due to code crash.
- Nova material count now shows in station designer.
- Added subfaction selector to change faction profile page.
- Ship weapons can be modified in space showdowns.

Edit: We forgot to add a note about the updated force training equations when using a master. The rules are available here.
