ace has ~800 warnings for the allow_no_extension change, but it's also easy enough to turn off

[BrettMayson]

They're all legit though? Some evening I could slap extensions on them. This PR should remove all the class ones, are there other false positives?

[PabstMirror]

I didn't notice any

Another possible issue would be if someone was doing dev builds with wav/png and then did final builds with wss/paa
Such that they want no extensions in the configs
but again they can just turn off the feature

[BrettMayson]

Ah, I suppose, I've never done that
