update 0.2.2

new stuff:

• Initial emc support. I studied some other gcodes finally, but they are not there yet :) . Also, I don't have a way to test emc file yet
• circle strategy added
• ported to blender 2.66 (some api changes and library builds)
• machine bounds are displayed now

fixes:

• Fixed operation depth, when the specified depth was deeper than actual object depth - I made it to respect the user's choice, not limiting it to the depth of object or material. (this is based on my own use case)
• Fixed spiral path - insideout option and conventional movement were behaving wrong.
• counter clockwise spindle direction for block and spiral strategy fixed.

Otherwise I did a lot of other background work , which is not visible yet. I made a better 3d silhouette algorithm, but it only works in some cases well, so I still have to work on int. Also working on better collision code.
