MVP Seed file created.
Small edits to _activecase.html.erb but will probably be discarded when we refactor CSS later.
typo fix
google_controller logic error fixed where responding defendant pages were not rendering back to original case page user was on when clicking google signin/signout.  Removed extra css/scss files we are not using.
Google/Evidence Flow fixes
- Rearranged evidence submission form so user logs into google signin first, then can enter an argument.
- Killed the photo url input tag since it's cut from MVP
- NOTE: AJAX workaround to preserve user input values in argument didn't work since Google signin redirects to google once.
