First release of my fork

It uses the 1.41.0_alpha2 + some commits of the prusa branch as the baseline.
If i forgot to remove some copyright things, let me know.

What's new?

• one perimeter in top surfaces
• Extra perimeter if needed: now add perimeter over overhangs (instead of doing nothing) & change the perimeter direction at each layer to get a better finish.
• much better thin walls
• avoid unsupported perimeter
• ironing
• denser infill below solid surface (kind of automatic infill density)
• Anchor solid infill by Xmm : It was harcoded to 3mm, now you can choose this value.
• infill before: now can be chosen by region (right-clic on an object)
• over-bridge flow ratio: let you fill the gap over the bridged section to have a leveled top layer.
• verbose output: now also write the needed coments for the octoprint CancelObject plugin
• "filament" option in the bottom left combobox in the preview view (a bit like "extruder")
• adjust the last layer(s) height to let the printed be at the exact size (only for the last layer, not all top layers)
• fan speed can be adjusted for the top surfaces

known issue

• seems i broke the support generator. the bugfix is ready for the next release.

notes

no mac build because i don't have a mac. you have to compile them.
no linux build (yet) because i'm lazy and linux users know how to compile things ;-p
