SVG Editor, gcodeviewer error & Label changes

I've added the SVG Editor and created a link from with-in OctoPrint. Corrected the issue with the gcode viewer scanning and crashing when it does not see extrusion values. And Changed 'Tools' to 'Laser' and edited in the M03 / M05 commands. And also edited the fan commands to line up with GRBL.

Obvously this is a WIP.
