Add a new InfoSystem that sends SharedInfo from the server to client
when requested. Currently, only the rule header and rule text is sent.
Previously, the rule header and rule text was bundled in the client,
which means that the client would only display rules that it was built
with, even if the server has different rules.
This allows servers all running the same build to send different rules.
This could be useful, for example, for servers running the official
builds to send different rulesets without a client rebuild.
