Made life in mil-land a little less painful.

- .fpd file format: new directive "unit" to set the default unit
- new selection was too aggressive - make it only rearrange settings if we also
  fail the second vector search
- gui_draw_pad_text: calculation of height vs. width lost too much precision,
  causing pad text to be rotated arbitrarily
- drag_new_vec: display distance in mil if unit is mil
- end_new_raw_vec: store distance in mil if unit is mil
- gridify: use a 10 mil grid if unit is mil
- ps_hline: corrected gsave/grestore mismatch
- Makefile: made "all" a prerequisite of "install"
- Postscript output now mentions the default unit (if set)
- ps_package: height and width were swapped, oopsie !
