Two new commands

Hi Tux!

I have added a couple commands for my own use with GriefPrevention, and believe they may be useful to others:

/resetclaims - this returns a player to a "like-new" state, as if they had just joined the server, by deleting all their claims and setting their accrued blocks bank back to the initial value provided by the config.yml file.

/setblockbank - this command manually sets the player's accrued blocks bank to a specified amount, proving more useful than using bonus blocks in cases where you need to distinguish between bonus blocks and normally-obtained blocks (e.g. bonus blocks being given for a prize, but actual blocks being taken for a punishment).

Let me know if you have any questions, and thank you!
