Added bower.json

There's some confusion over the name & git url of the module. components.json points to the old repo url. Both package.json and components.json name this module (and list in bower & npm registries) as dom-delegate, which now doesn't match with the ftdomdelegate name it's listed under in the origami registry or the repo's name.

I suggest the best way to deal with this is to revert to using the ftlabs/dom-delegate url and name universally and updating origami registry accordingly
