Things not yet supported properly in new-formats

[namida]

This post is basically just a checklist for myself / Nepster of what things remain to implement support for in the new-formats version (currently not publicly released). For now, this is only focused on features that exist in the current versions; features that are to be added specifically for new-formats will mostly come later (though some are already included as a direct result of the format change; eg. there's no longer a 16 character limit on graphic set / music filenames).

Just to be clear to everyone: This does NOT mean these features are being culled. Just that they aren't working properly in the current source code, and that we ideally need to restore them before even a public experimental, let alone a stable, new-formats build can be released.

Nepster: I don't mind taking care of all of these things, but if you do any of them, please strike them off this list. Likewise, if you find any others, please add them.
