51.iframe - WebKit porting to Mona OS

Found we were not able to tweet from our Webkit port. After investigating, we found iframe load failed. We probary missed setting up subframes, but we're not sure what was wrong.
So I asked about it at #webkit IRC channel. One of developers taught me that I should ckeck WebKit2. WeKit2 shows me how we setup frame and how we load content into it.
