Work on Hunter class

Added hunter class abilities not present in playtest. Hunter playtest
was not a spontaneous caster, fixed. Added known spells limits and
automatic spells "Summon Nature's Ally". Still a problem with
SPELLLIST:2|Druid|Ranger not working right. i.e. Ranger spells of lower
level than Druid spells are still not showing inthe proper lower level
spell list.
reverse !PRECAMPAIGN change
Merged in the warpriest set from advanced class guide playtest as a starting point
Missing parenthesis in equation
Corrected typos in PREABILITY and Slayer and Brawler weapon proficiency keys
Correct usage of DEFINE
Merge pull request #65 from mjmeans/pfs
