Django-pgtrigger

Trivial

- Updated with the latest template, dropped 3.6 supported, added Docker-based development [Wes Kendall, 25e0f0d]

Bug

- Ensure that generated postgres IDs are lowercase [Wes Kendall, 5c12f66]

django-pgtrigger now ensures that generated postgres IDs are
lowercase. Postgres IDs are case insensitive, and it django-pgtrigger
had issues dealing with names that had a mix of cases.

Feature

- Add the "declare" portion of a trigger as a top-level attribute [Wes Kendall, cd18512]

Previously one had to subclass a trigger and override ``get_declare`` in
order to change how the "DECLARE" fragment of a trigger was rendered.
Users can now provide ``declare`` to the instantiation of a trigger.

The documentation was updated to reflect this change.

Bug

- Throw errors on invalid trigger definitions. [Wes Kendall, 28f1329]

Previously triggers were installed with a broad try/except in order to ignore
errors when installing duplicate triggers. This caused invalid triggers to
not be installed with no errors thrown.

The code was updated to catch the specific exception for duplicate triggers
and allow other trigger errors to surface. A failing test case was
added.
