In RB 7.1 we added a setting to disallow users from saying "Ship It!" to

their own review requests. By default we had set this to disallow

because it makes sense that users shouldn't approve their own changes.

However, its a noticeable change from what we had before and I think

it'll surprise existing users too much. I myself got confused and wondered

where the Ship It! button went. This change enables this setting by default.

Ran unit tests.
Toggled the setting and saw that I couldn't self ship-it when disabled,

  saw that I could when enabled.
