MetalHeadCAM 0.3.0 released

Hi all,

I've just pushed MetalHeadCAM v0.3.0 to cam.metalheadcnc.com. I'd love to hear any and all feedback you have.

Just import a DXF file, then click the Add button in the operations panel. After that you should be able to simulate and export Gcode.

Since the last release:
- Much improved performance
- Added spot operations

I'm still not maintaining backwards compatibility, so if you've tried it before be sure to go to the hamburger menu in the top left corner > Settings > click Reset Application before use.
