A new type of PageList

A PageList where it is possible to define different Templates for different pagetypes. More of a proof-of-concept than anything else.

With will be used as follows in the aspx:

        </div> 
    </ItemTemplate>
    <PageTemplates>
        <Custom:PageTypeTemplateContainer PageTypeName="[Public]Article">
            <ItemTemplate>

                </div> 
            </ItemTemplate>
        </Custom:PageTypeTemplateContainer>
        <Custom:PageTypeTemplateContainer PageTypeId="11">
            <ItemTemplate>
                <div class="item" style="border: solid 1px blue;"> 
                    <h2><EPiServer:Property runat="server" PropertyName="PageLink" /></h2> 
                    <p><EPiServer:Property runat="server" PropertyName="MainIntro" /></p>
                    <p>Publisert: <%# ((EPiServer.Core.PageData)Container.DataItem).Created.ToString("dd.MM.yyyy") %></p>
                </div>

    </PageTemplates>

It is admittedly a bit heavy on the control nesting.
