This is a first rough commit for #95, adding the ability to embed YouTube videos in forum posts. Some more polish and testing needs to happen at this point. I wanted to get all these changes off my hard drive and into the repository.

div.weblinks-link-sort {
   padding-bottom: .5em;
}

ul.weblinks-link-options {
   margin: 0;
   padding-left: 0;
   list-style-type: none;
}

ul.weblinks-link-options li {
   display: inline;
   padding: 0 5px;
}
