tools/check: Add suite (message content) parser.

Some main benefits of adding both tools/content scripts to tools/check
are that you don't need to manage your directories for storing the
zuliprc files and corpuses, or specify any command line options for
fetching message contents and running the unimplemented features test.

The script is intended to be run manually, not as a part of the CI,
because it is very slow, and it relies on some out of tree files like
API configs (zuliprc files) and big dumps of chat history.

Fixes: zulip#190
