Merge pull request #516 from frymaster/worldeditor-changes

Improvements to checks for inventory blocks and double inventory blocks
Move null check in tool code one level out.  This means it will guard against trying to use worldedit for querying double chests when worldedit is not loaded. Fixes #511

Long-term, perhaps rather than using a worldedit object directly, we should use our own interface which supports similar methods and have two implementations, one which uses a worldedit selection and one which takes two corner coordinates for use in double chests.  That might also allow for custom queries along those lines.
