Change to assembly and sticker shortcut policy

[Orion Pobursky]

which parts are that for example? only shortcuts/stickers where all parts are already certified?
which users can fasttrack? can they fasttrack their own new parts?

Only Associate Admins (and above) can Fast Track. Admins to the have ability to FT their own parts.

For sticker shortcuts Fast Track is authorized if the sticker(s) and the base part are official or in a certified status.
For assemblies, Fast Track is authorized if the uncoloured assembly shortcut and all component parts are official or in a certified status.
