css changes and adding id ... nothing really
added remember me functionality

added to login and register -- not sure if this works; but we'll see
a medley of changes; see details

meals page: added id to content; changed meal button to an a tag
meals controller: scroll to top of page via $anchorScroll; determine
next suggested meal
edit meal controller: scroll to top of page via $anchorScroll (the page
was scrolling to the bottom if the page that called this page was
scrolled down a bit)
auth controller: removed listener for firebase login event (it was
causing redirects even on page refreshes because the event fired after
the refresh), now we just do the redirect upon initial login
lookup service: added a few more food types
