Remove modal login, fix signup and login partials

Remove bootstrap js modal login, since it turns out bootstrap doesn't
support adding js hooks to buttons within the modal, so I can't add a
"success" action to the login button in the modal. This feature will
have to be added as a later project using a home-made ajax-ified modal.

Move context specific text out of form partial and into respective view
page.

Display user info on user show page, fix typo in page header.
