Blender CAM 0.9.0 release

Finally, a new release!

I know the waiting has been long, and those who were in need of the updates, started allready using the version of Blender CAM from github.
There are many fixes, and many improvements, and also, many new features

this list is not really showing pictures, and also not everything that is in the release, but now, there are more people cooperating on the docs so I hope, the pictures will make it soon to the wiki pages which now grow quite fast on the Github wiki: https://github.com/vilemnovak/blendercam/wiki
big thanks for the wiki go to Jeff Doyle,who started this new documentation project.


larger features

V-carve test by Jeff Doyle

• Polygon library was replaced with shapely library completely. This was a huge task, touching almost all areas of blender CAM. 
• OpenCAMlib support by Karol Suprynowicz
• manual bridges placement - now you can define bridges with a group of curves.
• auto bridges placement was improved
• medial axis strategy - you can use this for V-carving and Ball-carving(not sure if that's the right name, but enables you to use the ball cutter for the same task).
• projecte curve strategy - this is a complex strategy that enables undercuts. Some docs will be needed.
• Intarsion tool modifies curves to be suitable for intarsion - the resulting shape can be cut inside/outside and will fit.
• Overcuts tool - this is experimental, adds simple overcuts to the curve object, good for fast setting up of slots. 
• several new postprocessors, most of them by new contributors!
• 4 axis code is enabled in experimental features, but it's still heavy WIP, and is released mainly to get more people communicating about it!

small features:

• experimental features can be switched off in addon preferences.
• curve remove doubles operator
• Denver Hull commited a patch which adds operation start-stop points and fixed some unit problems

I probably forgot a lot of what was done.

BIG THANKS
to all contributors, to people who communicated on the forums, who helped by donating money, to anybody using blender CAM :)

and SORRY to those I forgot to mention here. And to those to whose e-mails I forgot to reply...

Enjoy using BlenderCAM and stop by on github on the forum to let us know about bugs or your ideas.
