Bozarth prime/merge marlin 1.1.9

[BozarthPrime]

This PR gets the version of Marlin that this is running off of up to date with the latest stable release of Marlin 1.1.9 and incorporates some changes to add the M16 gcode command I added to Marlin 2.0 recently.

I have not fully tested this yet because I need help from you, @Silverquark on compiling the changes for the LCD panel. I added the new screen for the new error but I am not sure if I have to compile anything of that to make it work. There is the DWprj.hmi file which I added the screen in but there is also that binary DWprj.tft file that I am not sure about and was not finding any great information on. If you could advise on that that would be amazing.

The main goal of this was to get this project back up to date with the latest version of Marlin and sort of revive it. You did a lot of good work on this and I just want to say thank you for that.

Over yesterday I flashed the firmware to my machine and ran through everything aside from hitting the new screen I have not been able to flash yet and all is working great.

I am working in getting the Travis ci working correctly now

[BozarthPrime]

Fixed the travis ci and I have also updated the README but that will need to be updated with some path corrections before merging.

@nepeee Can you shed any light on how to build the tft files for the display?

[nepeee]

You need to use the DGUS SDK: https://community.advi3pp.com/t/resources/25
