Edit Mode: Rework display to differentiate selection modes 

This removes the large edges and instead use colors to hint in which
selection mode the user is.

The component in each individual selection mode is more prominent to add
more emphasis. The other components are less prominent and dimmed.

A minor default theme changes needed to be made to keep clarity in all
combinations.

Forcing old behavior (no selection mode hit) could be done quite easily
by just making the 2 booleans true (selectFaces and selectEdges).
