sqlite3.Connection.set_progress_handler()

docs: set_progress_handler(handler, n)
impl: set_progress_handler(progress_handler, n)


Apart from that, the rest of sqlite3.Connection seems to be ok.

There's an ongoing discussion at python-dev about how to resolve this issue. I'm in favour of normalising the create_*() methods to be positional only (like create_collation() is now).

sqlite3.Cursor and sqlite3.Row methods seems to be ok as well.
