Implement the loaddata Management Command

[GoogleCodeExporter]

We need to make loaddata work properly with the SA backends.  This could work 
fine already 
depending on the implementation, but we need to verify it.

Loaddata uses a connection.ops call to generate sql for reseting sequence, in
addition to using transactions. So most likely this will need customization.
