* Infer `foerign_key` when `inverse_of` is present

Automatically infer `foreign_key` on `has_one` and `has_many` associations when `inverse_of` is present.

When inverse of is present, rails has all the info it needs to figure out what the foreign_key on the associated model should be.  I can't imagine this breaking anything

* Update test models to remove redundant foreign_keys

* add changelog entry

* fix changelog grammar
