Optimized task group screen, faster. Added sort by name.

Opening tutorial now re-enables campaign tutorials.

Unstuckify: vehicles stuck in one place for too long now try to reverse and get out. Useful for fallen trees.

Gun Recoil: reduced for all artillery type guns by approx. -30%.
Recoil increased for all weapons for airborne units. Hardly noticeable for most units.

Makeshift DYI faction artillery units flipping from recoil is intended.

Changed main menu UI. 7 random pictures at loading. 1 out of 7 is pre-generated with AI.

Minor other adjustments, not to balance.
