WIP: drop bower task

Hiya! This is a work in progress PR about how the bower task works. Probably almost all of bower_components is unnecessary in dist, but I guess the usecase for this is to make assets like the bootstrap glyph font available? Could there be some cleaner method for this I wonder?

Also this change would drop the React bower dep since I guess there are no assets there to load?

Thanks for a great generator btw, two sales PoCs down and many more to come :D
