On edit spool page display remaining filament in grams#559

The remaining filament in grams is not displayed anywhere on the edit spool page, only the percentage. And when you change the “How much is left” field to grams the value stays as the percentage rather than converting to the remaining grams.

To make it worse, the edit spool page generally covers up the displayed grams remaining on the spool page (depending on the browser window size).
