Finally fix list_players command

Originally I made list_players return the full avatar
object rather than just the name string. Which was kind of
a bad idea because certain contents were unserializable
which caused the command to break (sometimes).

Weeks later, I attempted to fix it by returning to the
original behaviour of only returning names. By that point
I had forgotten that PSFPortal was changed to expect an
object.

So here's the final fix. player_list now returns a very
simple object made up of the name and faction id.
