Decorator for Django views that sends returned dict to render_to_response

Template name can be decorator parameter or TEMPLATE item in returned

- template: template name to use
- mimetype: content type to send in response headers
Examples:
# 1. Template name in decorator parameters
@render_to('template.html')
