Transform was still prototyped as having only one parameter in transform.h. Caused some warnings and possibly errors since some calls were missing the context.

The rest is proof of concept goody for a CONNECTED limiter for PET.
That is, PET affecting only elements which are connected together.

Only affects Curves right now since that was easier to test connectivity with. Still some polishing to do (falloff is based on distance of effect, not real distance), but it's a proof of concept, so...
