ShowAllSpellRanks causing range to be invalid when toggled. (#15)

The library internally in the spell checkers, e.g. checkers_Spell uses the "spell index". The spell index is actually the index into the player's spell book, not the spell id.

Toggling the "Show all ranks" toggle does change these indexes, since multiple ranks are shown, thus the checkers need to reinitialized.
