[CF-Devel] spell: town portal

[Mark Wedel]

 General suggestion:

 Please include a description of what any code patch submitted does.  It makes
it much more useful.

 Looking at the code, it appears it lets players create 2 and only 2 gates that
are linked back to each other.  Thus, someone could set up a gate that goes from
scorn to santo dominion.  It also appears that anyone can use the gates so
created.

 One question/concern:  Is there any checks such that players can make their
link from say their apartments (where the gate will exist for ever) to some
really juicy treasure chamber?  Such that the player logs in each day (or every
2 hours really) hops through the gates, grabs the treasure, and logs out again?
