specification/metadata-3.2: Update spec per discussions in #ircv3
metadata-3.2: Significant reworking of the spec.

* Require metadata-notify CAP for notifications
* Replace NOTIFY verb with incoming METADATA verb
* Remove custom data: crap.
* Add METADATA key for RPL_ISUPPORT
* Adjust subcommand targets; they are now mandatory, but '*' is
  accepted and channel collectives are supported.
* Clarify that server.* key space may have restricted visibility.
specification/metadata-3.2: Another major revision.

* Removed subscriptions in favour of MONITOR.
* Removed LIST-FORMAT because it was terrible and I feel terrible for
  entertaining it.
* Removed channel/user globbing from the target list, since MONITOR
  obviates it.
* LIST-SET is LIST once again.
* Miscellaneous formatting fixes.
Copy MONITOR spec from Charybdis documentation as a companion to metadata.
