Bug fixes, own collection.

While examining icons, I noticed material icons were too dark.
It appeared a lot of bad hacks were added for colormanagement in preview render.

Removed them all, and things look smooth (yes, color management is OK!).

However! It is now very clear that Procedural Textures miss getting inverse
color managed in render - a reason why they show so bright washed out, already
since introduction of Color Management in Blender.

Try render a plane with linear black-white blend, shadeless!

Todo: add colormanaged procedurals (optional).
