Updated copy, disabled buttons, swapped out LIVES header

- Updated copy written by Jack & AJW

- Removed buttons and references to buttons that linked to LIVES
forms…commented out the code until a simliar form is created.

- Swapped out LIVES banner IMG with placeholder banner IMG. The copy we
want, but I'm not sure that we want the icon.

- Don't have logos/seals for participating cities. Thus, did not change.
