/*****************************************************
 *
 * WorldCommModule
 *
 *
 * Holding place for world comms - basically llListen
 * function implementation.
 *
 * lLListen(integer channel, string name, key id, string msg)
 * The name, id, and msg arguments specify the filtering
 * criteria. You can pass the empty string
 * (or NULL_KEY for id) for these to set a completely
 * open filter; this causes the listen() event handler to be
 * invoked for all chat on the channel. To listen only
 * for chat spoken by a specific object or avatar,
 * specify the name and/or id arguments. To listen
 * only for a specific command, specify the
 * (case-sensitive) msg argument. If msg is not empty,
 * listener will only hear strings which are exactly equal
 * to msg. You can also use all the arguments to establish
 * the most restrictive filtering criteria.
 *
 * It might be useful for each listener to maintain a message
 * digest, with a list of recent messages by UUID.  This can
 * be used to prevent in-world repeater loops.  However, the
 * linden functions do not have this capability, so for now
 * thats the way it works.
 * Instead it blocks messages originating from the same prim.
 * (not Object!)
 *
 * For LSL compliance, note the following:
 * (Tested again 1.21.1 on May 2, 2008)
 * 1. 'id' has to be parsed into a UUID. None-UUID keys are
 *    to be replaced by the ZeroID key. (Well, TryParse does
 *    that for us.
 * 2. Setting up an listen event from the same script, with the
 *    same filter settings (including step 1), returns the same
 *    handle as the original filter.
 * 3. (TODO) handles should be script-local. Starting from 1.
 *    Might be actually easier to map the global handle into
 *    script-local handle in the ScriptEngine. Not sure if its
 *    worth the effort tho.
