Using HTML Helpers can cut down on repetitive code

Looks like there was a lot of code repeated in the views..Html Helpers can cut that down a lot..
I've just added the extension methods to *HtmlHelperExtensions* and created the helper *UserHtmlHelper* and its reduced the code quite a lot already.

```
new style:
  @Html.User().Avatar(profilePicUrl, new { @class = "span3", style = "margin-right:10px;" })

old style:
@if (String.IsNullOrEmpty(@item.ProfilePicUrl))
{
  <img src="../../Content/templatemo_329_blue_urban/images/facebook-avatar.png" class="thumbnail span2" />
}
 else
{
  <img src="@Url.Content(@item.ProfilePicUrl)" alt ="" class="thumbnail span2" />
}

```
