- delete.c: added more destructor functions

- deallocate all our data structures on exit (to help find memory leaks, bad
  pointers, and general logic errors)
- fixed memory leak when allocating pad names in instantiation
- added "magic" environment variable FPED_NO_GUI to run fped without 
  initializing Gtk+
- added valgrind wrapper "leakcheck"
- delete.c: destroy() now requires a deletion to exist
- vacate_op: free string expressions
- destroy_obj: free measurement labels
- delete_references: use do_delete_obj so the we don't bump the group number
- delete_frame: delete references after deleting the frame itself, so they end
  up on the stack above the frame and get destroyed first
- do_delete_vec: like above, even though it doesn't matter here
