Brief: //dnl ch86

- Fixing mapeditor move building and improving some related mapeditor stuff.
Details:
- Change the way exit grids are add, remove, save and load through editor, also add undo option for exit grids and you can place unlimited number of them.
- Fix incorrect gridno save in temporary map file for bigmap exit grids.
- Increase maximum number of light sprite from 256 to 4096 per map.
- Using DEL key for QuickEraseMapTile will now erase ItemPool too, and with improved function DeleteStuffFromMapTile will erase light sprites, exit grids and door locks.
- Cliff hang tiles used for middle cliffs are now possible to erase with when erase button is on.
- Add support for undo door locks, also you can now erase them if erase button is on.
- Move building function is completely rewrite and will properly move exit grids, door locks, lights and items too.
- Removing unnecessary tiles during copy building is improved too.
- Fix undo function for light sprites which now will also store all three types and undo them properly.
- Fix CTD situation if tile elements are deleted and after that items too, then undo will crash mapeditor.
- Fix spawning of item pool cursors during when adding items.
- Fix text glitches over door locks form.
- Fix sticky tooltip when loadsave screen or door locks form is active.
- High ground marking cursors will not be drawn in invisible map tiles anymore to increase speed and maybe fix some render problems but I doubt it.
- Move GLOCK_17_ForUseWithLOS item generation from init.cpp to los.cpp to avoid potential problems if global world items array not set.
