One could add a new frame if a frame with an underscore as its name already

Browse Source 
existed, thus creating a structure that could be saved but no longer loaded.
Likewise, one could add new variables/loops/columns if there was already one
named "_", thus creating the same problem.

- gui_frame.c (pop_up_frame): disable "Add frame" if we already have a frame
  named "_"
- gui_frame.c (pop_up_frame): disable "Add variable" and "Add loop" if we 
  already have a variable or loop named "_"
- gui_frame.c (pop_up_single_var, pop_up_table_var): disable "Add column" if
  we already have a variable or loop named "_"
