Solution for: #64: facebook feed update complains about img objects

Facebook doesn't like % in URLs

-4
This took some time to debug: apparently Facebook doesn't like percent-encoded URLs, so if you sent it some feed template code that looks like

{ "body":"blah blah", "images":[{ "src":"http://img.awsomeness.com/8484%2B9087453jpg", "href":"http://awsomeness.com" }], }

it will complain about the percent-encoded "+" in the img src. You can easily unescape in ruby:

>> URI.unescape("http://img.awsomeness.com/8484%2B9087453jpg") => "http://img.awsomeness.com/8484+9087453jpg"
