Title: Added support for .S files when building firmware

I wanted to use some AVR assembly sources in an Arduino sketch, and was surprised to see Ino doesn't handle .S files by default.
I think it's a low-impact change and it does what it should, so I was hoping you would consider merging this feature upstream.
