Included Portuguese language

Dialogs from M119 translated, and "Set Preheat" dialogs adapted to the
screen size.

Changed to report on individual lines with "TRIGGERED" or "open" instead of "H" or "L" on one line as H&L could be confused with logic levels High and Low which may be wrong if using inverted logic.  Added strings to language.h.

Fixed typo "deu" in English language that was fixed in #134 but got added back in via 9f7f7354f5

Some dialogs corrected and Default language set to 1
