Puni

* Added optional `lazy` keyword argument to all UserNotes instance methods that update the usernotes wiki page or the usernotes cache

Example:

python
un.remove_user('shadowbanned_user', lazy=True)

This release contains nearly no changes from 0.4.1, but I feel confident enough to upgrade puni to "full release" status.

- Fixed 5

- Fix problem with `get_notes()` where notes' time would not be set
