Cleanup: Get rid of context in editor 'new' callback

Requiring context means we can't easily create new editors to replace deprecated
ones in versioning code.
Think it's reasonable to give editors access to scene and area data for their
initial setup though. They mostly need it for setting "the view", as in,
scrolling values.

Also did minor cleanup in top-bar creation function.
