Newznab adder

Basic yet functional Newznab automation

It really needs some work on the overlay it produces (as design is not my area), but it will overlay on sites we detect as Newznab and offer the user the ability to add it to their sabconnect++ settings.

The user can click close and it will return on refresh. They can click ignore and it won't return.

Enable it and it will refresh the page with sabconnect++ features.

Only problem, but not so much a problem is that you can't unignore (but you can still manually specify the site in the prefs)
