Add option for Realtime Get

[arrpee]

From the docs:

The realtime get feature allows retrieval (by unique-key) of the latest version of any documents without the associated cost of reopening a searcher. This is primarily useful when using Solr as a NoSQL data store and not just a search index.

A query might be:

query := solr.NewQuery()
query.Q("id:123")
s := si.Search(query)
res, err := s.Result(nil)

while a similar get request is:

q := NewQuery()
q.AddParam("id", "123")
s := si.Search(q)
res, err := s.RealTimeGet(nil)

Any thoughts?
