Permissions: user emissions with a given actor
Created originally on Bitbucket by cdevienne (Christophe de Vienne)
We need some user accounts to be able to emit as if a given actor is theirs.
2 use cases:
- an administrator need to emit a message for testing purpose.
- a 'basic' user needs to emit a message, possibly through a web UI.
When doing so, the account id would be saved so we always know the origin of a message.
