Turn master spells into a data contained by a facet.
	Greatly simplifies (setting up for removal) Globals.getSpellsIn
	Change in Bob test case is due to recognition that SPELLLEVEL items allow known spells (was missed in current code - the previous output was based solely on the global list (CLASSES/DOMAINS in Spell LST), not those provided by SPELLLEVEL/SPELLKNOWN)
	Change in Prereq tests was due to a "timing issue" in that the the test was out of sync with core behavior.  CLASSES and DOMAINS equivalents were input after the character was created, so moving those to additionalSetUp (so it happens before the PC is created) solved the issue and allows data to be pushed through the facets, not pulled by Globals.
Issue#: CODE-1974
