Adds a sidebar widget to display Website uptime using Pingdom, with which you must have an account and api key.
WP Pingdom brings the power of Pingdom's automatic site monitoring to your WordPress blog, allowing you to include your uptime statistics on your blog in textual or graphical form. The remote calls to Pingdom and the graph image are cached, so the Widget should not affect your site's performance.
