Added OrientDB 1.6 libraries
Added OrientDB config files
Added OrientDB entity interfaces and abstract classes for a full EntityDatasourceFactory
Updated EntityFindBase abstract methods to fix support for custom extensions like OrientDB, was broken as part of recent TransactionCache changes
Added nosql datasource that uses OrientDB by default
Added tasks to clean, load, reload OrientDB databases
Changed ArtifactHit to use nosql database, somewhat risky as this is experimental but seems to be working well
Small fix to lib refs so that example tests run
