Update the docs to show some of the configurable things that were otherwise hidden in the source.
Add support for sponsors.
Don't modify the passed in object; instead, copy it before making changes.
Attendease will now send a long a bunch of has_foo booleans to indicate if the event has foo (e.g. sponsors, presenters, etc). If there are no foo, don't request foo from Attendease. This should speed up publishing a bit for some events that don't have foo.
Start moving away from redundantly-namespaced variables such as site.attendease.data.attendease_foo. For now, we'll just make site.attendease.data.attendease_foo as site.attendease.data.foo.
Normalize and better-name some of the override configuration variables. As well, use sprintf to allow the overridden titles include the actual value (using %s):

    venue_page_title: "Venue: %s"
Output nicer filenames for presenters and venues.
Template rendering fixes.
Attendease will also set the default path names.
Ensure we're using the Event's locale for translations.
Sponsors index page.
Link and invalid HTML fixes.
Output update.
Add a filters module.
Version bump.
