Comprehensive Illusion Fixes

* All player attacks now check for safety and guild attack validity on
created illusions, as tested against the creator of the illusions. Wall
Elements also follow these safety rules when attempting to affect
Reflections and Evil Twins. If you cannot attack a player, you also
cannot attack their illusions, and neither can your walls.

* Dispel Illusion now passes the caster of the spell to the room dispel
functions, which now test the caster's safety and guild status against
the owner of the illusions. If you cannot attack a player, you cannot
dispel his personal illusionary enchantments, and you cannot dispel his
reflections, illusionary firewalls, or evil twins.

* You can now go orange by casting Dispel Illusion with your safety off,
or by attacking an innocent's reflection directly. You can still dispel
your own illusions and attack your own reflections without penalty. Note
that you'll only go orange if you are successful at dispelling an
illusion. Failed attempts won't check against your safety status. You
can even still cast dispel in the inn, it just won't dispel anything.

Reflection streamlining:

* Implemented a direct server setting for the max reflection per caster
count, default 2. Upgraded the 'count reflections' metric by having it
directly count a player's reflections from the master server list. A
player may now have only 2 reflections anywhere in the world at one
time. Admins can change this setting at will.

* You cannot create reflections in guild combat rooms if you are not a
valid combatant, nor can you bring them in from another room. Safe areas
are valid spots for reflections cast by anyone.

* Reflections now change rooms with their creator no matter where they
are on the screen.

Combined, these 3 reflection changes make the spell far more
streamlined. The creator is free to be as mobile as he wishes and the
reflections will follow. There also won't be any mules casting
reflections (since you can't get rid of them if you can't attack the
person) and unguildeds won't be able to cast or bring reflections into
town. I think the Reflection streamlining is appropriate given the new
restrictions on Dispel Illusion.
