Thanks for this! I've currently pulled this into my local branch and am cleaning up the code style so it matches the rest of the repository.

I also realized that before I release a new version this will need to support WorldGuard. My current best guess for doing so involves learning BlockChangeDelegate from:

Sorry if I played with your code too much, I just got started on tweaking and got carried away. Thanks much for the idea and base code.

I'm tracking the need for WorldGuard support with issue #27

A couple of other ideas that I'd like to implement:

• Error message if generateTree failed. (Done)
• Support for administrator defined possible tree types. (Added with 994da88)
• Investigate if sapling is best default for new tool. (Changed to Gold Hoe in 6c8013a)
• Support WorldGuard. (Added with 61d67a3)
