Condensed, extra condensed, compressed variants.

I love Source Sans Pro and use it on my UI work every time I need something clean, legible, neutral and modern. However, there are cases where a condensed/extra condensed/compressed variant would help a lot, making this family even more versatile. This isn't a trivial request, but if no one asked for it yet, I'll gladly be the first: please, consider making these variants at some point if at all possible.

Thank you for such a good open typeface!
