Remove special cases for unused awards.

Removes the following awards / fields on User:
 - flairlock
 - progressivestack
 - bird
 - longpost (pizzashill)
 - marseyawarded
 - rehab
 - deflector
 - mute
 - unmutable
 - eye (All-Seeing Eye)
 - alt (Alt-Seeing Eye)

Primarily motivated by starting to remove some un-Mottelike cruft
from core commenting/posting routes. Cleared out other inapplicable
awards while in the process.
