Ability to turn off retraction

[wbarber69]

I would like to give linear advance a try with dual colors. but with no retraction enabled filaswitch doesnt work.

Does fs crash when disabling retraction? It might be that the retraction values aren't in the header when it's disabled and header parsing fails...

About LA: I've been running LA for some time, I even ran the LA calibration g-code to get the correct value. However, I still need some retraction, otherwise it oozes. Also ProStruders don't seem to be best extruders for LA, they sound kinda horrible with LA enabled and K-value 200. I need to drop print acceleration to 500 to get the noise down, with higher acceleration the extruders doesn't seem to be able to keep up.

Linear advance has had some improvements since I see you are using high values. LA values are now much smaller. My LA value is 1.6. Still there may be an instance where I need to turn retraction off and yes fs crashes with no retraction enabled.

I haven't upgraded to Marlin 1.1.9 yet so still going with the high K values. I understood that the new LA code in 1.1.9 automatically adjusts the accelerations. I'll need to check that later.

I'll have a look at the retractionless settings, it's a bug and needs to be fixed.

Fix committed to master, processes fine on my test model. Not tested in print, though

Good man! Will give it a go tonight.
