Much thanks to Thomas Reynolds and Buck Wilson for their help and advice on this.
Disabling text selection is made possible by Mathias Bynens http://mathiasbynens.be/ and his noSelect plugin, https://github.com/mathiasbynens/jquery-noselect, which is embedded.
Tyler Akins (@fidian) has also rewritten chunks of the plugin, helped close many issues, and ensured version 2 got out the door.
