Add bower.json to properly support bower install

[miensol]

It would be nice to be able to install and use debug through bower directly from source repository.

To make it available in bower it would have to registered and ideally a new release would be created (to enable proper install by bower install visionmedia/debug --save)

Not really interested to be honest… but do I need to do anything like publish to a bower repository or anything like that?

Actually visionmedia/debug package is already published in bower - not sure by whom. Bower will look at repository tags to identify releases and at bower.json version property - and will complain if those don't match. So the version in bower.json would need to be updated when releasing new version.
