3.1.3-RC1 firmware for Prusa i3 MK3

3.1.3-RC1 firmware version originated as fix to 3.1.2 firmware version, because there was bug in setting extrusion multiplier, which in many cases would lead to over-extrusion.

Description of changes:

Extrusion multiplier fix:

In 3.1.2 firmware version, there was bug which caused, that extrusion multiplier was always set to 100%. This firmware version fixes this bug.

Selftest:

In previous firmware versions, axes checks were very sensitive, which sometimes causes that selftest was failing even in cases that printer harware was ok. This was happening usually on x axis.
In current fimrware version, sensitivity of axes checks were decreased.

Temperature calibration:

At the beginning of temperature calibration, there are warnings shown on LCD that user should run this calibration in certain conditions and without steel sheet. In previous firmware version, when user confirmed these messages with pressing the knob, LCD screen didn't refresh and last message stay present during calibration. This has been fixed in current firmware version and also it is now easier for user to remove steel sheet at the beginning of temperature calibration. In case that steel sheet is present, printer moves printing head and heatbed to certain position.
