Improve loading speed of stash (by Moa)

- improved processing of sector stash (opening/closing)
- improved loading speed of save games
- improved processing of items droped by militia (most noteable after autoresolve)
- and some other code related changes
see: http://www.ja-galaxy-forum.com/board/ubbthreads.php/topics/325332/FIX_improve_loading_speed_of_s.html#Post325332

Notes:
removed some functions, still in code so but renamed to *_OLD() because they are from Sirtech and should be kept as I have read in "§18) If possible, we don't just delete the old code, but comment it out (or #ifdef it out) for reference. We delete it only if it's really necessary."
