Publ v0.7.26 released

Here’s some new bugfixes and features!

• OpenGraph tags now validate per the W3C validator
• Images can now take a value of link=True in order to force a link to the full-size rendition without setting a lightbox gallery ID
• Links will no longer include the template name if it’s the same as the category default (so you no longer need to do annoying things like view.link(template=template if template.name != 'index')
• Similarly, path-alias to the index template will now work correctly if the category’s default template is not index
