Allow skipping deleted/nonexistent clips when loading a project
Submitted by 100domicil

I deleted a clip from my hdd then tried to open my project which was using this clip. Pitivi asked my where to find this clip. As I could only answer 'cancel' the project couldn't open anymore.
It should be tolerant to this kind of erros !
