Django-easy-audit

This includes an additional fix that (due to changes on the on commit handling on `CRUDEvent` creation, if there was an error and the logger tried to log it, it was possible that instance's `repr`/`str` would have included something that was already deleted (this is a consumer level issue), so now we will `try/except` on the logger and pass if we have an error (not wonderful for now, but easier to just do that and get the release out).

Default fix on the changed_fields conditional (if no changed fields, not making a CRUDEvent), not to use the newer flow (you may turn on the newer flow with a new settings toggle), via PR 129

This is likely the last beta release for 1.2.2.

Adds pluggable logging/auditing support (not just database, but could do logging, elasticsearch, etc). database is the default. This was on PR 124 thanks to atakanarikan

changeset also includes from release v1.2.2b1, but for brevity not included here.

Fix 106 from issue 97

Fixes 119 , all clients use the same code path, but now split DB users will have the bug fixed, so long as they adjust the db setting that the project exposes.
