[Shotwell] contribution copyright

[Xavi]

Hi,
thank you very much for your answers they've been very clear. Now I've 
got the information that I needed to know. And it would be so useful for 
me as may projects acts like Yorba in copyright issue.

I'm a shotwell fun and I wanted to use your ("our") project like an 
example of non copyright assignment compulsory neither necessary !! 
Thanks for extra information about the reason why Yorba choose LGPL.

Xavi
