Remove "relative_mode", only use "axis_relative_modes"

Browse Source 
axis_relative_modes can cleanly handle G90/G91 and M82/M83 without the
need of "relative_mode" entirely.

Change G90/G91 to simply reset all axes according to the requested
state, which avoids to check two variables in get_coordinates(),
fixing the following incorrect handling:

G91   ; all axis relative
M83   ; set extruder absolute
G1 E1 ; should be an absolute move, but still relative
