Pythoncard GUI revamp and focal region auto-detect

GUI changes to allow network mode access.   Several components removed
and their functions placed in options menu. Updated cfg.py to work with
changes.

Focal regions vs. focal points now auto-detected in compute.py rather
than set in gui.
Minor change to report_menu_files

One case with network mode wasn't showing up in console report, now
fixed.
