Branch/transform tool

This brings the transformTool up to date with development.  There is one commit which exposes the 'parent' property for vwf objects.  The current vwf model API doesn't support moveChild which I believe will be added.
  
https://github.com/virtual-world-framework/vwf/commit/de1575995dc9159cab103e0cd1ddd0d69bfb9e1e

public/tt is the example application.  The camera's far and near clipping zones need to be increased, otherwise it looks like the objects dissapear.

Usage: add the following behavior to the root of the application

implements:
- http://vwf.example.com/transformToolManager.vwf



To enable/disable set property:

transformTool-enabled = true/false
