EPIC: Default tray UI things

Question to @marmarta: What is the max-size each Tray icon's artwork should be created at? 16x16 is the smallest, and I know you need each multiple-of-8 thereafter; to a point. What may I ask is that point—128x128?

Also: Is there a hover state and a selected/open state, or just the latter?

[marmarta]

@ninavizz 64x64 is enough - this is the maximum the widget can handle; and while in theory a hover state may possible be implementable, we never use it, so selected/open and normal is all.

We have projects now, so we no longer have to (ab)use issues for this purpose.

I've made a project for this and added all appropriate issues:
