Macro start_print reorder extruder pre-temp

[stephbellemare]

Hello, i,ve re-ordered the pre-heating commands for the hotend, considering if you had pre-heated to unload / load filament, your macro would have to wait for the extruder to cool down, and then re-start heating back up. this is the way i've done it

{% if svv.setup_version|float < version|float %}
    { action_raise_error("Setup data is older than macro version
    You should check the values in INIT_SETUP and run it to update
    ")}
{% endif %}
{% if svv.setup_use_bed_offset == 1  %}
    BED_DETAILS # tell us about the bed
{else}

{% endif %}

I agree there is a problem there, but I'm using the extruder heating (or cooling) to idle temp as a "wait a bit and let the bed settle at print temperature" as if I don't the bed can still be settling and creeping when I start the mesh.
