[alpha] slimfast edition

The current stable release is the 2.2.53.4

new

• If possible, an extra perimeter is extruded instead of a fat gapfill, to be able to stay below the perimeter width without overextruding.
  
• you can now name your extruder (only used in klipper for toolchange)
• #663 add ru translation thanks to @VectorPort
• I now update the .pot at the same time the version is updated, so you can use the one packaged in the software, so you won't need to compile it yourself for updating the translation.
• update linux doc for raspberry pi (to test/review)
• change icons to blue

bugfix

• now the "check for application updates" works again and will link the correct website
• now settings will be printed as previously in the end of the gcode (from the hotfix)
• fix crash when exiting if you have changed the extruder count (from the hotfix)
• fix physical printer dialog (from the hotfix)
• fields can again span the entire width (pushed to prusaslicer)
• fix windows dll load: now use the SuperSlicer.dll instead of slic3r.dll (prevent a naming problem with the macos build)
• #659 fix fan mover that has problem when the printer was without relative extrusion
• #658 fix position of "points" widget
• fix layer time color
• fix color print preview
• update to freecad: don't save temp path, call arrange if >1
• #661 fix support overhangs
• #651 fix holes in small pillars that were are wrongly filled (boost::voronoi weird bug)
• #305 fix brim height (bug when the first layer height was a %)
• #673, now klipper TURN_OFF_HEATERS is equivalent to M104 S0 for the gcode viewer
• #674 correct standby temperature: now temperature + ooze prevention variation temp (previously toolchange temperature but this field isn't a stanby temperature it's a 'remove filament' temperature)
• #671 typo

note: I haven't tested the linux & macos build.
