It was filling the number.envelope prior to adding the envelope to the
mailbox, but wasn't actually including that change in the %message(s)
update that was getting sent out.
This makes +append-envelope return both the updated mailbox _and_ the
modified envelope, which we then use in our outgoing update.

Instead of providing a (unit path), allows for (list path), which better
supports the "update to path and subpath cases".
For example, if /things wants updates about everything, and
/things/specific wants updates about the specific thing, they'll both
need to receive a %fact when the specific thing changes.
Previously, these would have been two separate moves. Now, gall handles
the multi-targeting for you.
Sending a %code letter without output would cause its code to be evaluated on
the recipients' ships. While that shouldn't naturally occur post-#2009, and
evaluation of %code letters remains virtualized, it's still remote code
execution, and worth fixing as such.
