It was really a lot of work :D Took me the complete weekend :D Would really like to here your opinion on this =) The aim of this is to put all the actions for one block in one place so it is not spread around the source. (ToPickup, Action in cWorld, Action in cChunk, Action here, action there :D) git-svn-id: http://mc-server.googlecode.com/svn/trunk@671 0a769ca7-a7f5-676a-18bf-c427514a06d6
