Added more portraits and did a compability update to west 81

Fixed Krasnopol and Clustershells so they approximately work. Its not the best solution but atleast they are useable.

Fixed invisible FRG Breed soldier faces.

Changed the AI scripts to conform with current scripts. this means you will no longer get different divisions when facing NATO or Warsawpact but now the units are mixed together.

This however allows the frontlines gamemode to work flawlessly. So now that works.

Added Soviet 1945 Infantry variants to be spawning in conquest concurrently with 1950-1960 soviet infantry to simulate different quality units and equipment levels. First 5 matches are with 1945 and after that its 50% chance to spawn the new ones until match 15 when 1960s infantry takes over.

Fixed M113 and M113 ACAV HMG turret rotation.

Fixed ZU-23-2 properties.

Added bunch more icons for research tree and for units.

Finally probably managed to fix tons of bugs relating to the skimish factions and the mod.
