Surprises while checking language file

[Davide Ardizzoia]

Hello All,
I am polishing and adding to the italian translation provided by Max72 (thanks!), and found some issues:

1) have no way to translate all slider/drop down) content :
     -the support settings (coarse,rough,dense...)
     -raft type
     -prime pillar
     -infill type

2) No way to translate extruder map

3) No way to translate settings recap

4) BUT FOUND THIS:

This pattern will be printed<LF>in each corner of your bed.<LF>It will work from the top down<LF>pausing between each parallel<LF>pair of lines.  Stop when the gap<LF>is the same width as the lines.

WHAT IS IT ?!?

Best Regards
