Larva Queue Late Joiner Nerf (#3803)

# About the pull request

This PR makes it so players who haven't played yet have their join time
recorded, and that is used for their initial sorting value rather than
0. This means late joiners will be at the back of the line as if they
had just died.

This PR also fixes an oversight where ghosting as a facehugger would
count as death. Even though they really shouldn't be ghosting when
alive, they still shouldn't be penalized as far as the queue is
concerned.

# Explain why it's good for the game

Its not; its a bad experience for everyone that hasn't even gotten one
life in the round. However it seems I'm in the minority thinking that a
xeno shouldn't squander their first life and that death shouldn't bear
more consequences.

The new informational message if you press join as xeno while currently
ineligible to be a xeno candidate:
