Made major changes to the structure of the app.  Also added logic/styling/layout for homepage and controller for the backend to check credentials of the localstorage.
Changed splash page image to background-image.
Moved all modules related to participants into a separate js file and corrected routing.  Expect much of the preexisting modules to be somewhat broken with these changes, although this should be a fairly simple fix.
Added login page and styling.
Finished setting up the signin page and the backend for signing in.  Also fixed errors in check_credentials.php.
Finished writing most of the functionality for the signup page; however, little to nothing has been tested at this point.  Also, I add a list of interests and the filepath to each icon to script.js as a service.
Most of signup page should now be working, although it is missing a password field.
Frontend now has password fields and validation.
Backend support for password is now in place and all errors are returned when present as opposed to one at a time each time the form is submitted.
Added the directory page, modified all controllers to user $window.location.href instead of $location, added modified the header to be more compatible, and made a standard css file for all future pages.
Added the frankbook_directory page.
Added git ignore and modifed frankbook, which used to be participant_carousel.
