[Bf-python] New MH GUI using draw.LEFTBUTTON evt!

[Manuel Bastioni]

Thanks to Draw.LEFTMOUSE handler, and only using a script linked to 
scene redraw, Paolo Colombo from MH team has done a complex and 
perfectly integrated interface in MH 3D win.

Please, take a look here:

note the CPU practically don't work, because no loop are needed. The 
core of interface is like:

if QTest():
     evt, val = QRead()
         if evt == Draw.LEFTMOUSE: #THIS IS THE EVENT WE NEED
             x,y = GetMouseCoords()
             print x,y

when a redraw happen, if leftmouse is pressed too, the script work...
Simple and...powerful. The GUI has requested about 3 months of work, but 
really we are proud of result. This is possible only thanks the 
leftbutton event handler...it's really a great function!

If the url above is down (I can't use project.blender.org to host files, 
because it's 6 MB and the max upload size on bf is 4, so if a lot of 
people download the last release, I'm not sure the server resist) you 
can see a quick movie from here:
