Updated some errors where the wrong enemy Troop was triggered for boss battles

Fixed some items so they would actually do something when used

Updated goblin move set so Bodyslam attack is used far less frequently (fuck those guys)

Added multiple classes to play as (Spellblade, Knight, Martial Artist, and Wretch).

-Spellblade uses the same equipment as swordsman, but can use magic to augment attacks with elemental damage. Allows for more variety in combat

-Knight replaces Swordsman as the non-magic melee class, allowing access to heavier armor and higher defensive stats

-Martial Artist does exactly what it says on the can. More variety

-Wretch unlocks no skills as they level up, can only use a knife, and basic armors. Truly a waste of space

Added character select menu to opening text so players can pick their class

Added equipment to Cadence Store NPC for the new classes

Removed "Encounter Down" item from rare items store, as random encounters are no longer part of the game.
