Profile pictures (and other profile stuff)

Now that #40 is done, we can start this! :D

Added bios and editing them (+ admin perms to edit other users' bios from the site)

Changing usernames seems to be a much bigger issue since that'd affect DB lookups and stuff. I'll just add profile pictures and do the username stuff on a separate branch afterwards.

Stuff left to do:

• Fix XSS
• Profile Pictures

Inside of articles, sparks and capsules change
author: name
to
author: UUID from users
and in existing queries; ?

to reduce problems with any lookups in the future and make name changes possible;

Closing because it's only relevant to the old branch. This one was basically done anyway, though, minus UI stuff to allow changing it.
