Dopesheet-Timeline: Removal of Timeline Editor!

This commit removes all references to the old timeline editor.

Unfortuantely, the removal of the Timeline spacetype defining
functions has ended up breaking the version patching code I'd
been working on earlier (as now, the editor gets marked as
"unknown/info" before we get a chance to patch it!)
