Allow multi-line description in GCT editor
GCT load/save changes - see commit description

When reading TXT, treat codes starting with asterisk (*) as enabled, and others as disabled.
When saving TXT, save both checked and unchecked codes (checked codes will have the asterisks).
When saving GCT, save only checked codes.
If no codes are marked with "* " in the txt file, enable them all
I don't know how to fix this, but I might as well show a warning so I don't forget about it
Actually, this might be the problem
