[V3 Modlog] add events for modlog cases (#1717)

* Give modlog case objects the bot as an attribute

* Dispatch modlog_case_create and modlog_case_edit events

* case.bot, not just bot

* fix a couple more issues resulting from refactor

* Case.edit doesn't need the bot parameter lol

* Make create_case return the case object (because tests)

* Modify create_case docstring

* Fix a docstring
