change category on (3) -> invalid

Reason: The on tag has no meaning on its own, and should be invalidated. Though I'm not against changing its category instead if that's what people want.

Edit: Changed it so it changes the category to invalid instead of aliasing it.

I think a category change would be better.

agree; I prefer that in general so one can see if it was supposed to be part of a valid tag that failed to autocomplete, was accidentally typed with a space instead of an underscore, etc

I don't think aliasing is a bad move here.
"On" is entirely dependent on other tags to actually provide meaning. "anthro on human" (without underscores) will come out to "anthro human invalid_tag", "on back" will come out to "back invalid_tag" (back is already categorized as invalid), and then I could see combos like "on drugs" occasionally getting tagged (which would then become "invalid_tag drugs".)

+1

Reminds me of when I find stuff like *_pentration/*_penetated and 'back' as tags.
