multiple same-named parameters

[Erik Hatcher]

In my application I'm POSTing into the Solr for querying, and need to  
specify any number of "constraints" (which correspond to BitSet  
filters that get combined into a BitDocSet as a filter on the  
query).  Rather than have the client uniquely name each of the  
parameters, I want to name them all "constraint" in the request.  The  
servlet API supports this, but SolrQueryRequest currently does not.   
I've patched my local copy with the following and it all works fine.   
For LocalSolrQueryRequest, since it is using a Map for the arguments  
anyway, I simply added the new getParams method to return a single  
item array.

Any objections to me committing this?
Thanks,
        Erik
