Version 0.96b

- M82 and M83 no longer reset the reported extruder positions
- Moved print factor implementation (extrusion+speed) to the Move class
- GCodes: All codes will report replies with a '\n' at the end
- Calling M106 with no arguments reports current fan value in per cent
- M112 (Emergency Reset) doesn't send a reply to the web interface
- Webserver reports raw extruder positions without any modifiers applied to improve filament-based estimation.
  This also fixes a bug where the web interface would report incorrect filament-based progress if Cura G-Code files with
  more than 10000mm filament usage were printed (Cura generates G92 to reset it).
- Current fan value is reported to the web interface
- Bug fix: M552 always reported network to be enabled, even if it wasn't
- Other minor changes
