[Feature Request] Automatically Enable AltColor for a table if the folder exists

[Ltek]

Having an automated function to enable AltColor on tables would be VERY helpful for all - vets and noobies.

Doing 1 table at a time is tedious and confusing for Noobies since there is 1000x to know/do for vPin setup/config

Idea is :: if the folder exists under "vpinmame\altcolor", DMDext automatically enables 'external DMD' for that table.
