For the Marlin firmware, the machine envelope G-code is emitted

Browse source 
based on the Slic3r printer profile.

Also the bundled config has been updated, so that the machine envelope
G-code values were removed and the new Slic3r printer profile values
were updated with the former G-code values.

Slic3r version has been bumped up to 1.41.0-alpha for the configuration
files to work.
