* Adding the Tree module configuration options to OpenSim.ini.example

* Adding an option to use the tree module to manage the trees in the simulator (grow/reproduce/die)
* Setting it to off by default in an effort to reduce the number of threads in use by default
* You can also turn it on in a 'one off' way with 'tree active true' on the console. To 'one off' turn it off, it's 'tree active false'.  The permanent way to do that, however is in the opensim.ini.
