Main changes are:
* Files are saved as PNG so you can see a thumbnail of what is in the scene in Windows Explorer
* Sculpting brushes are much higher quality when sculpting on the centre line of a Mirrored Sculpt
* New shortcut to orbit the scene - Hold Middle and Right buttons at once and drag to orbit
Also fixed:
- Blob mirror offset broken
- Point to Point on Lasso tool
