Revert conference "tool" misfeature

This was added as part of a mass copyright header update in commit
6e7d5d08.  That's obviously not the right way to add features, so
we're reverting this.

If this feature is actually desired, it should be added in its own
commit, properly described in the commit message, and documented.

(The commit added a "tool" flag that could be applied to a conference
participant to mess with that person by disrupting his or her audio.)

This partially reverts commit 6e7d5d08.

This feature earlier tried to sneak in under the guise of a whitespace
cleanup in commit a000749e which
Anthony reverted at commit a24f9aa8.

Let's not play these games.
