Add versioning to bundles Some other bundle-related changes were made, including: * Editing the snippetform CSS and HTML to allow bundle/form.djhtml to be reused for editing * Changing {% block title %} to {% block section %} in the base template for bundles to allow for more flexibility when creating breadcrumbs * Saved common URL patterns in variables in bundle/urls.py * Renamed explore.html to explore.djhtml for consistency You should now be able to upload new versions as well as view the files (or a particular file) for a bundle at a specific version. Coming soon: the ability to add a timestamp and a comment for each new uploaded version (if this feature is desirable).
