Merge pull request #5 from andrepl/master

Adds support for Postgresql 9.1+

added GriefPrevention.ClaimCleanup.Enabled Option, defaults to true. Setting to false disables the Claim Cleanup tasks entirely.

added configuration options to disable entity cleanup, made spam control options use configurable commands rather then always kicking and banning
fixed broken plugin.yml. Move along, nothing to see here...
