Modified the map_setcell() code to to use a boolean flag instead of needing SET_ / CLR_ pairs of defines (topic:174323).

Also removed script object 'setcell', added script function 'setcell'.
- Now you can manipulate cell information without needing @loadnpc
- You can also manipulate the terrain ('gat') type itself, using the new cell_walkable, cell_shootable and cell_water constants
  (currently the implementation uses bit flags too, so to get the type you want, you need to adjust the flags one by one)
- This breaks current scripts, so please adjust places that use setcell
  (also be sure to _only_ use predefined constants, not direct numbers)
- Details can be found in the script reference.
