Description of Change

This PR creates a method inside the Tile Proxy Model to create instances of EditLog en masse given a list of Tiles, bulk_save_edits. The implementation presented in this PR is via the Resource proxy model bulk_save method, which creates Tiles en masse via bulk_create and naturally should create edits en masse as well.
