Implemented persistent world and map variables

The gameserver now receive a copy of all world state variables when
they are accepted by the accountserver and receive a copy of all
map state variables of a map when they register it successfully.

Implemented LUA script bindings for getting and setting these variables.

When such a variable is set, the accountserver is notified about this
change. Changes to world state variables are then propagated to all
gameservers by the accountserver.

Be aware that when a gameserver is updating a map, there is no check if
it is actually responsible for said map. But I consider this not a
security flaw, because authenticated game servers are considered to be
trustworthy in a lot of other situations, too.

Also renamed "quest" to "character variable" in the sourcecode.
