Changed version-checker method once more to ensure the result is never a cached one
Added /wpurgeblock command, which you can use to remove a single block from a specified world and xyz coordinate from the database (this could be useful if you find a block of air or otherwise that is protected when it shouldn't be)
Added /wpurgeplayer command, which you can use to remove ALL of that player's logged blocks from the database, regardless of location and world.
Added watchblock.admin permission which you can give to a player or group through your permissions plugin to let them use /wpurgeplayer and /wpurgeblock (more commands may be added in the future, see documentation page for this plugin to see all permissions)
