feat(control): Do not show CO aliases in developer tools window

This hides aliases in the control model. Aliases are only for backwards
compatibility, so this reduces the risk that mapping developers use
these COs for new mappings.

This also removes a bunch of CO deprecation warnings when opening the
developer tools window or starting the QML interface.
