pyngcgui: allow configuring send_to_dir

touchy requires send_to_dir=~/linuxcnc/nc_files
other gui apps can use default of [DISPLAY]PROGRAM_PREFIX
With this patch, the gladevcp .ui file specifies:
    send_to_dir=None|touchy|full_path_to_dir
(using full_path_to_dir is provided for completeness but
should probably not be used often as unexpected behavior
could result if it is not in the specified subroutine_path.)

minor: hal_pyngcgui.py bugfix: g_progname missing, use g_module

also: update configs/sim/ngcgui/pyngcgui_* .ini and .ui files
Do not distribute an 'all rights reserved' file

.. revert to the version of cone.ngc before this one was checked in.
As far as I can tell, the two files are totally unrelated.
