allow for window resizing in OpenGL modes
New option: alienContainmentHasUpperLimit.
Default value: FALSE (OFF)
If it's true, then the upper limit of the Alien Containments is counted!
If it's false, then there is no upper limit. (only when at least one containment is exist)
fix for persistent mind control due to panic.
less hardcoding, more ruleset flexibility.

oh yeah, and modding possibilities for grenade launcher type behaviour.
this is totally not me trying to sneak in features i want for my mod :P
small fix for some panic related bugs

cleanup in pathfinding
Large Block limit for maps

should help prevent "unreachable ufo" scenario.
allow for map blocks to have a subtype

allow for landing zones to be used as generic terrain as well.
add a frequency to mapblocks

use it to weigh odds, and to limit how many times a map block may be used.
also a small refactor in the battlescapeGenerator to place the landing sites first.
small refactor in bgen

place all the large modules first, then fill in the gaps.
fix for weird caching issues.

let's hope.
- refactored voxelCheck
- back to cyberdiscs
- user-mode first person shot (invisible units won't appear on screen), plus colorcoded units.
- unit color tweaking for voxel dump and fpslook
