[WIP][OXCE][UFO] Build mods from Ethereal.

[Meridian]

I'll think about it. But not before the release of the option for "Fatigue" in OXCE.

The fatigue option was rejected already long ago and will not be implemented.

You can use the mana feature to simulate fatigue, like XCF or Piratez.

And if you want something more heavy-handed like forced medical leave after missions, that can be done already by the script hooks that run on returning from a battlescape mission.

Very pity.
I did not want to implement mana ... but apparently have to.

[Ethereal]

Update.

- Added mana, in the form of a new parameter "Concentration". The parameter is static, does not grow with experience and does not regenerate automatically. Concentration is consumed by all actions in battle, except for the use of hand-to-hand weapons. Some weapons deal damage to concentration. Some types of armor regenerate Concentration, but basically it is restored only at the base. There are chemicals too.
- Psi radar, in a mental shield and a large psi laboratory, can pinpoint alien bases at a short distance.
- Some minor improvements, bug fixes and a little rebalance.

[Ethereal]

Update.
  - Mostly minor fixes.
  - Heavy low-tech armor requires 2 AP to rotation. Disk-shaped units and some terrorists do not spend AP on rotation.
