Added "title" variables to all generated pages

I changed the top of my head.mako file to look like:

    <title>
    %if post and post.title:
    ${post.title} -
    %elif title:
    ${title} -
    %endif
    ${bf.config.blog.name}
    </title>

so that values of ${title} are incorporated into each page's <title> tag.
