Merge pull request #601 from mcmonkey4eva/master

Pull request for fixing of things
<l@location.find.blocks...> now get x and z 'centers' of the block.
Catch exception on animate. Probably invalid entity_type, etc.
DisplayItem now works! yay!
Allow npc object to be specified in trigger command, no longer require 'name' prefix for triggers.
Fix debug order for InstantQueues.
Make faceLocation use block location for starting point, change pitch slightly for more balanced head angle.
Allow . in tag contexts... (alternative to regex pattern)
Comment these out for now -- I believe dScript object is covering all the bases. Stop errors on usage of just <script>
Add ability to get List<dLocation> from dCuboid.
Update CopyBlockCommand (in progress of allowing cuboids to work with this command)
