Fixes mix-it/linkit#6 : use full bootstrap js from CDN. 

We would have now to choose our path: full-CDN or locally served resources. Cos' now it's a kind of weird mix with old pages referencing not served bootstrap-v1 components. Old pages should be fucked up. I preferred not to touch them to keep a reference on their JS requirements (on Bootstrap v1 components) before refactoring them.
