Feature request: Allow different keep types to be used by AI & Players in Skirmish

[Antstafer]

I've always found it weird how you can only use the different keep types in freebuild mode and are stuck with only the default 'Stone Keep' in skirmish/mp.

Natively you can convert a scenario map into a skirmish map in the editor, however playing the converted map will just turn the other keep types back into the 'Stone Keep'.

This would work only for human players, right? Is that what is desired?
