Fix and improve LCD value editing display
- Fix: When "100.0" changes to "99.0" the LCD shows "199.0" - Use 2 rows if needed on character LCD, (allowing longer labels… Germany, et. al.) - Known issue: A certain length label combined with a certain value drawing function could, for example, display 99.0 on 1 line, but 100.0 on two lines. Workaround would be to pass a nominal value size argument.
