add `move`, `delete` commands which simultaneously operate on term+type+namespace+patch having that name

[aryairani]

move Foo Bar

would perform an atomic (in a single causal step)

move.term Foo Bar
move.type Foo Bar
move.patch Foo Bar
move.namespace Foo Bar

and show a consolidated diff after.

If it moves multiple types of things, it should also let the user know how to undo and use individual move.* commands. 💙

Analogously with delete (if it doesn't already work this way).

Acceptance Criteria

• [ ] All changes should be part of a single causal step
• [ ] If any change would fail due to a name conflict, no changes should occur and the conflict should be printed
• [ ] Some commands don't apply, e.g. a patch called Foo doesn't exist, that's okay, ignore it.
• [ ] If NO commands would apply, (e.g. no changes would occur), we should display a message indicating that.
