Pull setting g_noFloorPal[] further down, into makepalookup().

Now passed as last arg 'noFloorPal' to makepalookup(). Used as follows:
- from loadlookups(): *false*, i.e. do take over floor pal.
- from generatefogpals() [default fog pals] and fillemptylookups(): *true*,
  i.e. don't take over floor pal
- from DEF 'fogpal': true
- from DEF 'makepalookup': take over flag from pal from which we are remapping,
  or set to true if remapping from pal 0
- (CROSSHAIR_PAL: true)

This should make the issue reported in

resolve in a natural manner.
