Disable WordPress XML-RFP (pingback)

In March there was a DDOS attack that used many (160,000) wordpress sites to flood other websites.  This was done because wordpress now has xml-rpc on by define.

It is possible to turn off xml-rpc using a plugin.

This adds a filter without the need of editing your own pages.
