Ref T603. Fixes T2823. This updates Paste and Macro.
- Paste
- Added default view policy.
- I didn't add a "create" policy, since I can't come up with any realistic scenario where you'd give users access to pastes but not let them create them.
- Macro
- Added a "manage" policy, which covers creating and editing macros. This lets an install only allow "People With An Approved Sense of Humor" or whatever to create macros.
- Removed the "edit" policy, since giving individual users access to specific macros doesn't make much sense to me.
- Changed the view policy to the "most public" policy the install allows.
- Added view policy information to the header.
Also fix a couple of minor things in Maniphest.
