Expose the "Entry" entity object in the ViewPost control

[jeremy-jameson]

To allow greater flexibility in Subtext skins, the "Entry" object should be made available to skin controls that want to format the fields differently or show additional fields.

For example, in order to format my blog posts using the hAtom microformat (https://www.technologytoolbox.com/blog/jjameson/archive/2011/11/09/building-technologytoolbox-com-part-5.aspx), the custom skin I developed for Technology Toolbox specifies the following in ViewPost.ascx:

<div id="blogPost">
    <div class="hentry">
        <h2 class="entry-title"><%= Entry.Title %><asp:HyperLink runat="server" ID="TitleUrl" Visible="false" />
            <asp:HyperLink runat="server" ID="editLink" /></h2>
        <ul class="post-info">
            <li class="published"><span class="label">Published </span><span class="value"><%=
                Entry.DateSyndicated.ToString("MMMM d, yyyy") %></span><span class="label"> at </span>
                <span class="value"><%= Entry.DateSyndicated.ToString("t") %></span></li>
            <li class="vcard author">by <span class="fn"><%= Entry.Author %></span></li>
            <li class="comments<%= Entry.FeedBackCount == 0 ? " none" : string.Empty %>"><a href="#postComments">
                <span class="label">Comments: </span><span class="value count"><%= Entry.FeedBackCount %></span></a></li>
            <li class="categories">
                <uc1:PostCategoryList runat="server" ID="Categories" /></li>
        </ul>
        <div class="entry-content">
            <asp:Literal ID="Body" runat="server" />
        </div>
        <div class="attachment" <%= (Entry.Enclosure == null
                || Entry.Enclosure.ShowWithPost == false) ? "style='display: none'" : "" %>>
            <h3>Attachment</h3>
            <p><asp:Label runat="server" ID="Enclosure" DisplaySize="true" /></p>
        </div>
    </div>
</div>
