[WIP] Display party candidates on the party's page.

[oddsson]

NOTE: This is work in process, it is by no means ready to be merged.

TODOS:

• Split candidates into kjördæmi.
• Make the default background colour of the avatars that do not have images the same colour as that candidates party colour.
• React Avatar fix; There is something broken, sometimes the initials are not shown but a star is shown instead.
