Update Start G-Code Commands within Mattercontrol on the Touch Interface & the Desktop environment

Issue: Loading of filament and extruder position jogging before a print would result in unintended retraction of filament from the extruder at the start of a print.

**Important: The start G-Code must also be updated in MatterControl Dashboard if using a computer to process 3D files as described in Process Large Files on MatterControl Dashboard and Add to Cloud Library for 3D Printing.
