Major update to Solrsharp

[Jeff Rodenburg <je...@gmail.com>]

A big update was just posted to the Solrsharp project.  This update now
provides for first-class support for highlighting in the library.

The implementation is really robust and provides the following features:

   - Structured highlight parameter assignment based on the SolrField
   object
   - Full access for all highlight parameters, on both an aggregate and
   per-field basis
   - Incorporation of highlighted values into the base search result
   records

All of the supplied documentation has been updated as well as the example
application in using the highlighting classes.

Please report any issues through JIRA.  Be sure to associate any issues with
the "C# client" component.

cheers,
