Phase disabled in GuildHalls and Arenas

Phase is right out in arenas, but it also doesn't quite make sense in
guild halls under any conditions. If phase time doesn't count down for
hall owners, they can just sit phased out and watch a hall takeover
while invincible. If attacking enemies can phase out, they can scout all
the guild defenses while invincible. Guild halls are a unique PvP
scenario, so they should be uniquely different from world PvP.

Let's just skip all that and prevent phasing in halls.

-- UPDATE:

Phase also now deletes all user reflections. They were sticking around,
invincible, but still attacking players. Hilarious, but very bad.
