Fix sorting for non-Latin alphabets

[Throne3d]

Galleries in particular, but it seems we're not respecting non-Latin characters when ordering things on the site. Would be good to implement some sorting algorithm that does something sane for most scripts - there must be a standard Unicode way to handle this, right? Possibly need a specific database collation to handle this?

Example (not ordered properly, ignores the Hangul):

민기 - Aesthetic
Aesthetic - Food
민기 - Icon Dump
민혁 - Minkwang
민기 - Misc.
