The helpers added in #367 are great, but they don't quite match up with
what's being done here. Maybe that's why I neglected to convert this
over to the new thing. Anywho, just use the closest newflangled match.
Previously, this functionality was implemented in context-dependent operators. Considering that Korman is becoming increasingly complex and is now generating entirely new objects (potentially with modifiers) as part of its export process, it was becoming cumbersome to use those operators.
This fixes review comments left on #367 that were caused by missing
pretends-to-be-a semantics. `BMeshObject` is intended to provide
pass-through access to `bpy.types.Object`'s attributes.
