fped/overlap.h
werner e6b2658a65 Added relaxation of pad overlap checking. Not GUI-settable yet.
- README, fpd.l, fpd.y: added directives "allow touch" and "allow overlap" to
  make overlap checking more permissive
- dump.c (dump_allow, dump): generate "allow" directive
- obj.h, obj.c (allow_overlap): added global variable for strictness of overlap
  checking
- overlap.h, overlap.c (overlap, ...), layer.h, layer.c (refine_layers):
  strictness of overlap checking is passed as an argument
- hole.c (check_through_hole), layer.h, layer.c (refine_copper), obj.c
  (instantiate): updated callers of "overlap" to provide "allow" argument
