Deleting things often left measurements behind. Fixed these bugs, enhanced %del

to also delete frames and items in other frames than the current one, and added
the corresponding regression tests.

- fpd.y, README: %del can now also delete frames
- test/del_frame: regression test for frame deletion
- fpd.y: moved all debug items into debug_item, so that they can be invoked
  after defining measurements
- README: clarified that object labels aren't entirely hidden in the GUI
- delete.c (delete_references): also delete measurements referencing the frame
  (test/del_frame)
- fpd.y (dbg_link_frame): described why we need base_frame in addition to 
  base_vec
- fpd.y, README: %del can now also reach into frames other than the current one
- delete.c (do_delete_vec): also delete references in the root frame, i.e.,
  measurements (tests/del_vec)

For debugging and regression tests, fped supports the following commands,
most of which mimick the effect of GUI operations:
%del <identifier>
%del <qualified-identifier>
%move <identifier> [<number>] <identifier>

%del and %move take as their first argument the name of the vector or
object to manipulate. For this purpose, also objects can be labeled.
%del removes the specified item. This can be a vector, an object, or
a frame. If the vector or object is in a different frame than the
current, its name is qualified with the frame name, e.g., "foo.obj".
Object labels behave like vector labels and share the same name space.
They are not shown anywhere in the GUI.
For this purpose, also objects can be labeled. Object labels behave like
vector labels and share the same name space. They are not normally
accessible in the GUI. (You can see them in the code view.)
%move sets an anchor point to the vector named as its last argument.
The anchor point is identified by index as follows:
%move take as its first argument the name of the vector or object to
manipulate. %move sets an anchor point to the vector named as its last
argument. The anchor point is identified by index as follows:
anchor index vec/frame line/rect/pad arc measurement
