View Source Upgrading to v0.6

Change Backpex.Fields.ManyToMany to Backpex.Fields.HasMany

With version 0.6, we have combined the Backpex.Fields.ManyToMany and Backpex.Fields.HasMany field. The functionality of the fields is now combined in the Backpex.Fields.HasMany field. The API of the field has not changed, so you can simply replace Backpex.Fields.ManyToMany with Backpex.Fields.HasMany in your resource configuration.
