Metafiles are checked last for selectability

[tikonen]

When mouse is moving check first everything else for selectability before metafiles. If nothing is selected only then check if cursor is inside any of the metafiles. Change makes a lot easier to select objects (especially wires) on top of images.

Selectable images are not drawn anymore over other objects but are merely outlined. Selectable text items are outlined for better user feedback.

This is a fix I've been requesting for years...
