Add filter by map compatibility, or at least vanilla vs bw

As a
User

I want to
Filter maps by vanilla vs brood war so I can look for vanilla only maps, or maps with scm filename

So that
I can look for vanilla maps before brood war came out

I'm not sure this will help you achieve your goal. scmd2 will save as .scm by default until you do something bw specific. So a lot of maps created since bw came out have been saved with .scm. I think your best bet is to use last modified date
