Crates sorted differently in Tree and context menu

[ronso0]

Appearantly special charcters in crate names are treated differently in Crate tree and tack context menu.

I have crates named like sub-genres and used whitespaces and special characters to have them sorted by mood/energy and not alphabetically.
For sub-genres this doesn't really bother me, but I have crate names like '_____samples' to force-push them to the top of the crates list.

Crate list sorting (numbers are just for illustration):
1 ___samples
2 .FiDT
3 JukeFooT easY Jazzz
4 JukeFooT PRO
5 JukeFoot Deeep
6 JukeFooT reAL

Context menu sorting:
2 .FiDT
4 JukeFooT PRO
3 JukeFooT easY Jazzz
6 JukeFooT reAL
5 JukeFoot Deeep
1 ___samples

It seems the crate list uses this sorting
- .
- _
- numbers
- letters, alphabetically & case-independent

Whereas the context menu sorts like this
- .
- 0-9
- A-Z
- _ (several '_' are regarded as one '_')
- a-z
