Scintillating Caves improvement: energy vortexes->teleport

[tiger_eye]

To make Scintillating Caves more interesting (and more friendly to beginning melee characters), I propose each level to have energy vortexes that, when moved onto, teleports you to a different, random energy vortex. Should speed up exploration a bit, and give players a peek at the potential of the energies used in the spellblaze.
