Support multiline format and adjust height slider to help

MaxLineCount is hardcoded to 1 in OutlinedTextBlock.UpdateFormattedText() if TextWrapping is None (default).

Slider maximum was increased but people should really be making changes like that in advanced settings since they're already in there changing the format to includen ewlines.

Closes #5
