Added aceedventure.com to sites using Mezzanine.
Added a has_home variable to templates for the page_menu template tag, which indicates whether a homepage object exists, and can be used for checking whether a hard-coded homepage link should exist in the menu template.
Update the default twitter query since it's been flooded by movie tweets.
Add a deprecation layer for settings in templates, and deprecate the PAGES_MENU_SHOW_ALL setting since it's too specific for a setting and can be implemented in one line in a template.
Added an example to the page menu docs of rendering a tree representing the current section of a site being viewed.
Merge
Don't need to uncheck in_menus for an editable homepage anymore, so remove the comment describing that.
Correctly handle file uploads in profile forms.
Alpha-sort options for the search form.
Remove Nimbis Services link for now

We haven't deployed our Mezzanine-based Nimbis Services site
into production yet (the old link was to a testing site that is only
used internally).

We'll add this back in once we go live with our Mezzanine site.
Also check BLOG_USE_FEATURED_IMAGE in templates when displaying blog post's featured image.
Merge
Added a sort_by template filter for general use.
Removed Slugged.Meta.ordering since it'll generally always be nuked by Meta on a subclass - and added correct ordering to BlogCategory.
Clean up BlogCategory.Meta.
Preserve slugs & URLs when pages are moved.
Remove obsolete reset_slugs().
Check overridden() when changing slug.
In set_parent(), call save() before get_slug().
Make slug changes propagate to all descendant pages.
