v0.5.0.0

Lots of minor changes, and major changes towards making the leveling
system work. Currently have "granting experience" and "updating the
guilds total experience" and "updating each persons guild contributions
count" working, just need to implement "detecting if a guilds total xp
has surpassed the required amount for their next level up, and level
that guild up".
