Antimony 0.7.9

Features:

• Dramatic speedup in mesh export
• Added experimental feature detection to mesh export (which finds edges and corners and pushes a vertex to keep them sharp)
• Another major speedup in loading large files
• Made export workflow more flexible:
  • In the graph view, create a node from the Export node category
  • Attach shapes to its inputs
  • Click the small arrow in the upper right of the node to run the export task
• Added 'Jump to node' on right-click (in either 3D or graph views)
• Improved documentation

Bugfixes:

• Fixed a few memory leaks of Python objects
• Cancelling an export with Escape now actually stops the export task
• Changed the way that images are drawn to prevent (?) QGraphicsScene crashes
• Removed multisampling to fix crashes on Yosemite with integrated GPUs.
