this is step 2 of 2 of the OpenSim.Region.Environment refactor.

Browse Source 
NOTHING has been deleted or moved off to forge at this point.  what
has happened is that OpenSim.Region.Environment.Modules has been split
in two:

- OpenSim.Region.CoreModules: all those modules that are either
  directly or indirectly referenced from  other  OpenSim packages, or
  that provide functionality that the OpenSim developer community
  considers core functionality:

      CoreModules/Agent/AssetTransaction
      CoreModules/Agent/Capabilities
      CoreModules/Agent/TextureDownload
      CoreModules/Agent/TextureSender
      CoreModules/Agent/TextureSender/Tests

/*****************************************************
*
* 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.
