Summary of problem description

actual behaviour

The materialeditor bundle is currently part of CoreUI.

expected behaviour

The materialeditor should be placed under Modules/Bundles. It is not an essential "Core" feature.

Cause of the bug

Wrong initial commit, probably not enough communication (this commit took place before the introduction of the core modification flag).

Proposed solution

Move the whole directory to Modules/Bundles.

Affected classes

No code changes will take place.

How will the bugfix get tested?

No code changes, so there is no need for new/modified unit tests.
