Some small simplifications

[notspiff]

Description

Just some code cleanup

• switch instead of if nests
• maps instead of if nests
• table instead of duplicated string formatting statements

Motivation and context

I was bored in the sun and figured I'd do some coding.

How has this been tested?

Buttons work in skins, search works in library.

What is the effect on users?

None

Afaik we usually only branch when reaching release candidate. We're still on the way to Beta 1 so I think it's fine to get it in earlier :)
But, your call :)
