Delete tool crash

[GoogleCodeExporter]

What steps will reproduce the problem?
1. start a new game
2. select the delete tool
3. click on an empty space within the block placement area

What is the expected output? 
No response

What do you see instead?
Game Crashes with essentially a null pointer error.  
The error is because the slot which delete is invoked on does not contain a
block to ghost out.  The delete tool should check to see if it applies to
the target slot.
