Partials for complete profile

Hey @chadwpry && @rjewell2200,

I created partials to eliminate some of the duplication in the signup/complete_profile view.  This was a great way to learn some HAML. 

This seems to be working fine for me locally, please review the changes that I've made and let me know if you have any comments/suggestions/feedback.

Thanks! 
Any reason for creating these variables instead of referencing the :profile or :bio keys in the locals hash/dictionary?
