Updated loot functions

All the loot functions are in place, and are tested. Now, to tie these
in with the compositor properly, add in the language stuff.
Back !

Other paid work is done, so now I am pushing on towards Alpha release.
Oh, I can see the light at the end of the tunnel, I think. I hope that
is light.. :D
A whole mess of updates

Very close to completing this release. Made a bunch of bugfixes and
tidying up of mission handler code, tidied up configs, added Common
functions for moving into ZCR in Beta, dynamic includes for language and
most importantly, entire structure tidied up and separated out crash
missions from mission handler functions. Also tidied up log messages
using ZFM_Common_Log which will tie in with the language functions.

Not functional, as I still haven't committed code for spawning unit
groups into Layout, but that's next. Also, not fully committed language
yet, but that's on the slab right now, so expect it soon. That will
translate output into your desired language for the crash mission and
for log messages.

Also, language files not yet committed.
