questpgr support for special level arrival messages (trunk only)

Suggested by <email deleted>.  The level compiler allows
MESSAGE directives to provide text given upon initial entry to particular
levels.  Modify the code that delivers them to support quest pager text
substitution.  It could also be tweaked to support deliver-by-popup-window
in addition to deliver-by-pline, but I didn't go that far.

     He also suggested revising the message for the Plane of Air, but it
seems ok to me.  Instead, I've changed the message for the Astral Plane to
announce that it holds "the High Temple of <your deity>" rather than the
quite lame "the High Temples of the aligned gods".
