Feature Request: Colored directories in the games menu

[siffland]

Now sure if it is possible, but in the menu it would be nice if the directories were a different color than the games for easier organization.

Allowing the core working to only see its own files (nestang sees .nes and snestang sees .sfc) would also be nice, but not sure if would be worth the effort, but having the directories different colors than the files would be helpful.

src/iosys/textdisp.v implements the text display. The 32x28 characters take up 896 bytes of BRAM. Adding 16 colors to each char would take an additional BRAM block. It should be okay since we still have BRAM left.
