Support variables in the `{% now %}` template tag

Feature Description

Allow passing a variable from the template context into the {% now %} template tag to allow dynamically choosing the formatting.

Problem

Django's {% now %} template tag currently only supports a hardcoded string format defined directly in the template, or one of a small number of specific settings. By supporting template variables, it would be possible to change the format dynamically (for example, based on a user's locale).

Additional Details

As I explain in my blog post, the now tag has some very weird behaviour caused by assuming the format will always be a string. By expanding to support variables, we can also clean up these weird edge-cases by raising a TemplateSyntaxError.

Implementation Suggestions

Several other template tags support variables, so it should be fairly easy to reuse their implementation of this.
