Fix some identity changes not broadcasting

Some places in the code still used the old `rooms.lobby.usersChanged`
flag, which no longer does anything.

This allows a program to follow the lobby log on a rolling basis
using `tail -F today.txt` rather than a considerably more complex
algorithm.

Fix Choice locking and Magic Room.

- Choice items now lock into a new move properly after losing the
original locked move (due to Mimic/Sketch/Transform)
- Choice items now continue locking into the original locked move (if
there was one) after Embargo, Klutz, or Magic Room's effects end
- General fixes to the priority of ignoring items
- Magic Room is now usable again
