No change required to upgrade to multiple databases. Aliases are used to describe the database and these can be manually registered or fall through to a default alias using connect. Made get_connection and get_db first class members of the connection class. Old style _get_connection and _get_db still supported. Refs: #84 #87 #93 #215
