Revorked stats from ground up. Each user can now have his/her own stats page. Personal stats must be old atleast 5 minutes to generate. No need to put that generation in crontab, it is done on demand.
Fixed bug with unpaid shares (db is not updating properly and dropping paid shares).
If no user is selected, only list of transactions is showed (not every address).
Also added swag footer, feel free to remove it if you really want to (it is in previous commit, forgot about that)
