Evaluate scalability of Solr results teaser presentation

I've added this to the events solr results hook to render a teaser instead.

http://drupalcode.org/project/commons_events.git/commit/4629fcb

Its not a fix-all, but its a start for 3.0. We should refactor so I'm not marking as fixed. I've also committed a new search-result.tpl to the commons_origins theme, and if you manually disable rich_snippets, the search results page should look good.

We ended up using this approach and hiding some duplicate fields in the theme layer.

I'd like to assess the scalability impact of this.
