Replace use of type('') with basestring.

The code didn't call setLocalTransaction(), so getTransaction() always
did the same thing as transaction.get().

essentially means a connection keep track of which objects from
the connection are modified, instead of transactions keeping track of that.
A good consequence hasn't yet been implemented:  if a connection is
closed with modifications still pending, we can detect that efficiently
now, and complain.

This changes the behavior slightly for invalidations.  A Connection
will receive invalidations even if it didn't have any modified objects
in the transaction, e.g. db.undo() or a read-only transaction.  For
this to work, it assumes that the thread that called db.open() is the
thread that is going to use the connection.  If this isn't true, the
synch argument to db.open() can be used to disable the new feature.

co-habitate later.
