Full support sqlalchemy.dialect

[klinkin]

To provide full support sqlalchemy.dialect need to implement all methods of interfaces.py, such as:

• get_colums
• get_table_names
• and etc

I started on this!

Hey right on, have at it. :)

We don't (yet?) have need for the full support, but I would be happy to help get it there. Let me know if you need anything from me!
