Title: Implement addHeader and addHeaders

Implement the addHeader and AddHeaders in the Http\Request and Http\Response classes.

According to the proposed FIG http message interface, the Http\Header class now uses arrays to store the headers and returns a string on getHeader() if the $asArray parameter is false or not set.
