1. in primary colors option changed gray to yellow.  2. added parameter
for themes (but with a choice of only one option.  Also added associated
language strings  3. added a spinner when loading that is removed upon
completion.  Used spin.js v 1.3.2 from http://fgnass.github.io/spin.js/
by Felix Gnass (@fgnass). 4. Bug fix: click through to event information
page not working on some CiviCRM installs.  5. make page redirection the
default instead of modal.
