Ultra Rando Mode Engage!

New Ultra Rando Mode!

New options for a "no holds barred" approach to player growth, enemy spells,
enemy zones, and spell learning. This makes them (almost) completely random.
All spells will be learned by level 20, and enemies in zones 0 and 1 are limited
to no tougher than scorpions.

This version also includes minor tweaks to zone randomization in normal mode.
