Import: a 3D model doesn't ask how to interpret its alpha (#264) 

Importing a glTF / OBJ model opened Interpret Footage: the probe
reports straight alpha and the file has no alpha label, so with
Settings ▸ Import ▸ Interpret Unlabeled Alpha As at Ask User (the
default) the model was listed as unlabeled. Only image footage
(stills, sequences, video) can have unlabeled alpha; a model renders
its own, and audio and data have none.

Test: importing_a_model_does_not_ask_about_alpha (engine).
