Subject: [PATCH] Add a minimum bed temperature of 0 degrees

If the bed temperature is less than 2, the print job fails with an
error message complaining about an invalid temperature. This happens,
for instance, when printing ABS where the bed is not supposed to be
heated.

This change makes sure that the bed temperature cannot be negative.
