Fix cherrypy URL and use HTTPS for twitter

[stonewareslord]

When When clicking the cherrypy.org URL, it routes to http://CHERRYPY/www.cherrypy.org. By specifying a protocol, it forces the page to be routed properly.

Also, Use https for the url and the Twitter URL for security reasons. I did not change the others because they do not support HTTPS or have valid certificates.
