N as I have no idea what week I am in.

[x] Improve JavaScript codes (or at least make it readable by others)
[x] Remove current user counter
[x] Make QR code url generator code easier to read.
[x] Get rid of user session and replace it with cookies (Where possible)
[x] nuke users in database so it'll use less resources (We only want to store a cookie based id)
