A2 Island Fixes addon

I spent some time to make A2 maps a little bit more playable and here is there result.

*added missing stringtables
*penetration materials - no more bulletproof walls or trees
*added vehicle dust & friction to a2 surfaces - moving vehicels & infantry leave dust and no more driving offroad like on highway
*falling walls
*remove a2 & a2co from mods menu
*working street lamps
