generally seems fine - thank you! If importing the components explodes violently, merge without changing it. I don't expect that they will explode, however.

[turt2live]

We should be able to import this (makes de-skinning a lot easier)

[kerryarchibald]

yay! i hate these

[turt2live]

import please

[kerryarchibald]

@turt2live unfortunately importing those components breaks the tests, so I'll leave that out of this change.
Attempted to get a component (${name}) before a skin has been loaded.
Will look into why/how to fix that in my next set of changes

[turt2live]

It'll be because skinning is terrible, so would recommend waiting for that system to just leave (which will swing by and fix it anyhow)
