Code

When editing a variable or value, the actual value is now shown. The choice

Browse Source 
of active frame reference, row, and loop instance affects this value, as it
should.

- obj.c (run_loops): reset loop->curr_value to UNDEF when instantiation is done
- obj.c (generate_frame): reset frame->curr_parent to NULL when instantiation
  is done
- expr.c (eval_var, eval_string_var): distinguish beteen instantiation and
  editing mode, and use "active" values in the latter
- gui_frame.c (edit_var, edit_value, edit_value_list): display the value of the
  variable or the active expression in the "X" field
- gui_frame.c (assignment_value_select_event, table_value_select_event,
  loop_from_select_event, loop_to_select_event): pass the frame to edit_value
  and edit_value_list
- expr.c (str_unit): since we may now accidently expose a wider range of
  exponents, removed -2 ... 2 exponent range limitation
