ArtNet support

Added ArtNet support to Lightwork-Mapper and Lightwork-Scraper.
The Mac OS X build includes Java - so there is no need to install Java on your machine.

For best results, install Processing and build the project from there. You may need to install Java for this to work.

LED Scraper MVP

This version reads an SVG file (from a hardcoded path...) and builds an OPC layout to drive LEDs on a connected FadeCandy board.

More Robust LED scraper

This release is a more robust scraper that reads in points from an SVG layout, normalizes them to the window size and ignores blank (0,0) points.
