started working on front end spec.
Merge branch 'master' of https://github.com/Lkoren/FlipOut

Merging work done on site for FlipOut backend with work done at home on the front end.
Mode selector page mocked out with Arial instead of intended font. Changed 'input type=button' to 'button' for the mode selectors, need to check if that needs to be coordinated in the server side code.
Added modes page.
Get and Post to login, main and mode all work. Sign logic has been reorganized slightly to make off site development easier.
Fixed authentication.
Finally got ajax callbacks working correctly.
Mode selector page with callback hook works correctly and renders more or less as intended.
Cleaned out extraneous files from the project.
CSS and HTML tweaks to the login page.
