label line breaks

[rastarr]

Hi and thanks for this project.
I do a fair amount of tech support and it would be helpful to be able to add line breaks in the label property of a key.

I've tried '\n' and the ANSI code already but they didn't work.

Being able to add line breaks allows me to better describe the pasted text (whereas currently, all the text gets smaller to fit on the one line)

Thanks again
