Diego Prado Gesto b6e997c88d CURA-4526 Delete LayerView plugin because it will be replaced with the
SimulationView.
This commit also adapts the code in order to accept the messages coming
from the engine, with information about feedrates and line thicknesses.
Add also some changes in the GCodeReader that reads feedrates and
line thickness from the gcode file.
