 * Announces who sprayed a logo. The spray action fires impulse 201, which this
 * plugin catches; it traces from the player's aim to the wall to locate the
 * decal, then prints the sprayer's name to everyone (or only to admins). A
 * per-player cooldown stops spray spam from flooding chat.
 *
 * Inspired by the classic Spray Detector plugins. Independent GPL
 * re-implementation.
