16x2 display: Show custom symbol for second profile

When the second config profile is active, we show an intervted "2"
symbol at the upper right corner of the main view.

Normally the break symbol is shown in that position.
If the user triggers the break, the break symbol
takes precedence over the custom "2" symbol.
