basically, there's no need to load all of these.

dunno why i removed it in the first place.

remove nonexistent properties from fonts.css, quote font name with spaces.

music info is messed up now, but kinda works

also fix header that was wrong.
add styles for titles with backlink.
& other changes (see diff, i'm lazy)

also snippet that makes art menu is now separated as mixin (very
powerful thing, btw).

much of stuff included here is subject to change.
