add support for a config file

[andy5995]

I wanted to suggest adding support for a config file...

Or better yet, maybe the python script could get a list of installed mods from the mods folder.

• Read each subfolder in ~/.local/share/0ad/mods
• Parse mod.json MOD_NAME="$(jq .name mod.json | tr -d \")") or the 'label' field.
• Do not recurse

mods-changer/0ad_mods_changer.py

Line 21 in 315bbdd

choices = [ KateGUIv5, whynot, StarGUI7, plus ]

no time for a extra config (may later)
