Add/delete items to a model with frame animations

[zturtleman]

I've added support for removing vertexes from models with frame animations in ec71320. I previously added support for adding and removing groups (just the name/material, not vertexes) and points in 6515b20 and fcf167a.

It's still missing support for adding vertexes (without having to use Model -> Merge). The commit for removing vertexes (ec71320) also fixed adding vertexes but it's still disallowed as create cube, cylinder, etc tools don't work properly yet.

Very cool, thank you.

To be honest, vertexes were the most important part of this. If I can delete a vertex, I can delete anything. ;)

Adding stuff via merge certainly works. It means a few more steps over being able to add items directly, but it's certainly doable. So you've already covered the most important aspects of this request/suggestion.

Thanks again.
