dashboard, search bar, payments history initial

- Tweaked the dashboard a bit. Made the text bigger, got rid of the
  colored numbers. Still want to do something about the account and
  logout buttons (push them further to the right).
- Changed the 'Search' button in the searchbar to 'Go!'
- Began changing the 'Print' and 'Email' form buttons under account
  summary->payments to use opac-buttons instead of default browser
  buttons.
