Includes a partially backwards-incompatible config change

Workaround for #661: this makes the `CAP LS 302` line from the default config
fit on a single line, as long as the server name is at most 35 characters.

tor-listeners.listeners was checked against listen,
but listen is obsolete now, so config load would fail
on a config that used the new style `listeners` instead of
`listen` --- unless tor-listeners.listeners was empty, which
it should be under the new style, but there's no need to enforce
that

1. DRY "banner" descriptions of each services
2. `/HELP NICKSERV` now refers the user to `/NICKSERV HELP`, etc.
3. Fix double translation of `textGenerator` output

1. Your own snomasks would be reported as belonging to the other user
2. Prefixes were incorrect
