New port: cad/k40-whisperer

GUI control software for the stock K40 laser cutter controller

K40 Whisperer is an alternative to the Laser Draw (LaserDRW) program that
comes with some Chinese laser cutters. It reads SVG and DXF files,
interprets the data and sends commands to the K40 controller to move the
laser head and control the laser accordingly. K40 Whisperer does not
require a USB key (dongle) to function.

Features:
- Reads SVG files and DXF files.
- Splits input design based on color formatting (red, blue).
- In SVG files blue and red paths are interpreted as vectors for vector
  engraving and cutting. Everything else is transferred as a raster image.
- In DXF files blue paths are interpreted as vector engrave (blue).
  Everything else is interpreted as vector cut (red).
- Performs cuts on features inside of other features before cutting the
  outside features. (If you cut the outside first the part might drop out
  of the stock material.)
- Converts gray scale images to halftone images to simulating varying
  levels of gray (i.e. engraving pictures). The Halftone option needs to be
  selected under "Raster"-"Settings" to enable halftoning.
