Bitly modifications:

- source_url now links information about the shortened link (how many times was it visited, referers [sic], etc.)

- It's harder to copy a link that's in an input box than it is to just copy a link that's in an anchor tag. Bitly plugin tries to detect if it's a mobile device, and it will show a link instead of an input box.

- Added a QR code.
Bitly: Bigger QR code, and I also added the original link.
