Спампаваць Voltius 0.18.0

Added
- Pasting a host into another vault now carries its key and identity across, so
the pasted host still connects instead of landing without credentials.
- useT and useSessionById are available to plugins from @voltius/ui.
Fixed
- Renaming a folder moved it into the Personal vault. Any folder kept in another
vault was silently relocated, taking everything filed in it along.
- Moving a key, identity, connection or folder to another vault unpinned it, as
did renaming or reparenting a folder.
- Members of a team vault received a passphrase-protected connection key without
its passphrase, so they could not connect. Both the current and the legacy
storage paths now publish it.
- The folder picker in the host, serial-host, key and identity editors offered
every page's folders, so a host could be filed into a keychain folder — the
editor then showed it in a folder its own page does not list, leaving it
sitting unfiled at the top level. Creating a folder from the key or identity
editor made a host folder for the same reason.
- Pasting a copied object no longer appends "(copy)" when nothing of that name
is there to collide with.
