Subject: * 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.
