Added cookies for checks on good sites

Cookies check if the user has been on the good-site in the last 30mins, stops spamming of +Gld/EXP on every page load. 
Added cookies for checks on vice sites

Same as good - checks if user has been on site recently in order to stop spamming on death.

E.g. its bad that you go on reddit, but it shouldn't punish you for each link it clicks on reddit - only for the 5mins. 
Fixed the interval for lingering
Fixed the timer from restart every page load

Current issues: 
The timer runs on each tab, so 5 tabs = 5 timers giving points.
The timer won't work for atm for quickly refreshing sites (required to stay on page for 30 seconds before a check happens)
Above can be fixed with a check on page load.
