Storing record data in a dict attribute instead of OrientRecord itself

[DeividasJackus]

My suggestion would be to have record data returned in a dict accessible through OrientRecord.data and keeping metadata like @Rid and @Version separate (OrientRecord.rid, OrientRecord.version). Returning query data as a dict instead of attributes should result in slightly more intuitive and easier data interaction during development.

Now the OrientRecord returns as a dictionary, the data are stored inside oRecordData key.
For backward compatibility, property access is maintained also.
