Added callbacks to futures
Forgot some files in examples/callbacks
Started authentication
Plain text auth support
Bind/Get by name
Added error for case when the name doesn't exist
Added some comments to clarify API use.

Also changed retain()/release() to inc_ref()/dec_ref(). I was too
confusing with ScopedRefPtr<>'s release() method. It also better says
what it's supposed to do. I also change Batch's list of statements to use
SharedRefPtr<> insterad of manually handling ref counts.
CassError is an enum
Perf improvements and map iterator
Added bind/get by name and future callback tests

Also cleaned up the use of boost::shared_ptr<> so that it’s way less
verbose
