Generate the entries table on the server side.
Use Solr instead of database to get the entries
Remove entry_query function as it isn't used any longer
Provide search function on the entry index page
Show facets in template

This also changes the expand_facets method so that it doesn't work
with a mutable argument but becomes a class method for the solr browser
Add filters to the entry index and make facets clickable
Add facets to the entry table to make it at least a little bit more
readable to users
Small interface changes and moved things around to make the code cleaner
Made default behaviour show from and to dimensions in the table
and fallback to showing facets.
