Winter Slash [new minigame]

New features:

• Added titles
• Fixed class armor
• Improved freezing (still might work on that a bit)
• Added random arena join option
• Killstreaks & killcounts
• Rounds

Bug Fixes:

• Players now get correct classes
• Classes are returned after death
• No double items
• Items no longer drop on death
• Added separate class just to track round progression

• Some warnings may appear but they don't influence gameplay (no known crashes so far!)
• if there are errors on the first run a reload should fix them
• title commands will spam anyone with op: "command executed successfully"
