Update to config.md

[vincode-io]

While trying to get a test version of feedBase up and running I hit a problem. The feedBase.io services were getting called instead of my test server. To fix the problem I had to add something like the following to my config.json:

"homepage": {
      "pagetitle": "feedBase",
      "urlTwitterServer": "http://hellofeeds.com:3300/"
},

I thought you might want to know incase you wanted to update the config.md document with it.

edit: forgot the pageTitle which is also needed

Thanks for the tip, I'll take a look and report back.

Another thing that tripped me up was that the myPort variable isn't being used by davetwitter.js. I had to include my port number in the myDomain variable to get a valid callback URL for Twitter.

I don't know if this just needs to be documented differently in config.md or if it is an enhancement for davetwitter.js, so I'm piggybacking on this issue.
