fix(bower): rename component.json to bower.json

Hey ho,

changed my component.json to bower.json and got exception from this plugin.
Running "cdnify:dist" (cdnify) task
Warning: Unable to read "component.json" file (Error code: ENOENT). Use --force to continue.

I forked the bower-test branch and added the fixes their.
I think you will merge this soon.

Every other change that is needed would provoke a merge conflict.
