fix(publisher): corrected main path

I finally took the time to do it...
I added a `bowerData` key to the client publishers to overwrite any existing bower properties in the built output (we you run `grunt build:bower`).
This fix exits in `angular-ui-publisher@1.1.1` and `angular-ui-publisher@1.2.4` so old and new repos can use it.

Closes #177, #161, #157
