New: SSL support

- sprymedia.co.uk now has an SSL certificate, so Visual Event will work
  on SSL sites now (which it previously didn't due to protocol
  differences (https page trying to load http).

- Small changes needed to load the target scripts on the same protocol.
  Unfortunatly this does require an update to the bootmarklet, so folks
  already using it will need to update.
Merge branch 'master' of github.com:DataTables/VisualEvent
