Allow MANGOHUD_CONFIG to override configuration files' settings.

Browse Source 
Use `MANGOHUD_CONFIG=some_setting=1` to skip reading the configuration files
and just use the settings specified with MANGOHUD_CONFIG.

Use `MANGOHUD_CONFIG=read_configs,...` to read configuration files too and
add other settings that you would like to override.
