added success to getting_started.  fixed birthday selectors to display years down to 1930.  made buttons rounder.  all save and continue buttons step forward.

Conflicts:
	app/controllers/users_controller.rb
	app/views/users/_account.haml
	app/views/users/_profile.haml

settings are more restful with account settings submitting to users#update, and profile settings submitting to person#update

removed javascript slider.  made each getting_started section its own page.  added bio to profile (and changed xml_accessors to xml_readers).
