[Front-end] Begun enforcing the sharing of data between controllers to be strictly in services. Modified filter module such that, going back a page maintains its state on UI (But the filtering is broken on cardModule page). Added a stub in app.js where we can run and save state by writing any services we want to sessionStorage.
[Front-end] Fixed up the padding on the left/right side for mobile login/reg, migrated more css code to less code.
