Override dict's get method

[dominickj-tdi]

This allows the get method to be able to work with remote databases. Currently calling get only returns a doc if it is in the cache. The original behavior is preserved by use of the remote parameter, consistent with other overridden methods such as keys(), therefore this should be a non-breaking change.

Description

Currently, calling the get() method on a database object returns None, even for documents I know exist in the database. This was because the method had not been overridden, therefore was only returning documents from the cache. With this change, it should now be possible to use the get() method on databases, rather than try/except blocks.

Approach

The code simply wraps a try/except block over the __getitem__ () when the remote paramaeter is True, and falls back to the original behavior by calling super if it is False.

Schema & API Changes

Updated the CouchDatabase.get() method, adding a remote parameter for that method

Security and Privacy

No Change

Testing

Existing tests should suffice for this change, because it makes no large changes, it is only a shorthand for calling an existing method.

Monitoring and Logging

No Change

@dominickj-tdi we appreciate your implementation.

We had to extend it with some tests, so I brought your commits into #505. Now you can find your code as part of 436eddb. I'm closing this PR.
