gmoccapy_0_9_9_6_2 - new plasma operation panel

ver- 0.9.9.6.2
- added a lot of hal pin to gmoccapy_plasma,
  with the new plasma.py file
- reworked the plasma.glade file to fit Marius needs
- new order of configs, many files have been moved by Dewey Garret
pickconfig: bugfix for debug_pickconfig

initialize ::myconfigs_node
and eliminate unneeded, duplicated var ::myconfigs

i think bug occurs only for
  rip with debug_pickconfig environmental set
sim/gmoccapy/gmoccapy_plasma update

The updated configs directory structure necessitates the following
changes that will allow a runnable sim config to run in both
a RIP build and from an installed deb:

  1) inifile references to nc_files dir must be ../../nc_files

  2) inifile references to parent directories will not, in
     general, work in an installed deb since there is
     no guarantee the parent will exist, so
       replace SUBROUTINE_PATH=../gmoccapy/macros
       with    SUBROUTINE_PATH=./macros

     AND (since the macros dir is shared with the parent)
     create a link so that
        ./macros --> ../gmoccapy/macros
     This link allows ./macros resolution in a RIP install.

  The configuration picker (pickconfig.tcl) will now
  follow a link to a subdirectory and copy the contents
  to the user config dir when the config is selected.
  (This is a new behavior that allows configurations
   to have subdirectories copied to the user config
   directory.  Note that such subdirectories
   may NOT include an .ini file or they would be
   detected as independent configurations).

  See configs/maintainer.txt for additional information.
