login dropdown

[lorensr]

current:

i propose we remove the dropdown when logged out (keeping it for now when logged in) and replace with two links like github does:

and both sign in and sign up do the same thing—start the github login process. we don't need to show sign up to people who have signed up before, so we could:

A- on sign in, localStorage.setItem('existingUser', true)
B- show sign up unless localStorage.getItem('existingUser')

thoughts? ways to make this UX better?
