Log Message:
-----------
Fix for 2 bugs:
 - Setting any of the branch lengths to 0.0 results in divide by zero. Min value for the length setting is now 0.000001
 - Preset export failed with the change to the way that vector properties were stored. Now we just store a slice copy of the vector in the export.
