to suppress subscription failure events in addition to subscription success, as
well as event forwards (though those shouldn't, in theory, go out over a new
connection because subscribers are cleared when a connection is dropped).
Nothing else looked like it might result in a spurious message being sent if a
connection was dropped and reestablished, so none of the other calls were made
to supply an expected connection.

on one connection, then disconnects. While that request is in the
pipeline, it reconnects, then receives the subcription that the first
connection requested before it sends its own subscription requests. To
prevent this, make sure that the current connection is the same one
that made the request.

Narya's strict approach to over the wire compatibility is not so nice when you
have cross-language clients that can't be updated at the same time as the
server.
Maybe we should consider a new over-the-wire format for C++ clients that is
more like pbuffers, which the Narya server could translate to and from Java
Streamable instances, and the C++ side could either use pbuffers directly or
have a similarly change resilient I/O layer that turned over-the-wire data into
C++ objects that mirrored (a potentially out of date) version of their Java
counterparts.

Events originating in Actionscript need to use that class because
we have no generic List class in actionscript. For things that
originate on the server this isn't a problem:
java array -> Array, and java List -> Array
But for things originating on the actionscript client, any array
will become a java array unless we use StreamableArrayList.
So: maybe it's time to add List to the aspirin library. :|

I was interpreting the lack of modification for $Id lines being people not setting auto props, but
it was actually svn not showing diffs for things it generates. Whoops.

If checking="true" on them, they generate their code to a String instead of a file, and compare that
against existing output. If any generation would produce changes, the build is failed.
As a side effect, generation will now only write files if it's going to modify them, which should
eliminate some spurious compiling.

Any Collection can now be streamed. You can send Collections.emptyMap()
back to a client, for example.
(It will unstream as a HashMap on the other side.)
This actually streams everything to the exact same bytes as before.
Using specific classes is discouraged: ArrayList, StreamableArrayList...
If a Streamer is created for a class that has a field of that type,
a warning will be generated, urging you to change the field definition
to the interface.
Also: that setup is now deferred until needed, because in clyde/projectx
there are a number of Streamable classes that have fields of specific
classes, like ArrayIntSet for example, but don't use standard streaming
to transmit them. In that case it's totally cool for them to have a more
specific type.
Since that setup is potentially deferred, one change may be observed
for a class that uses custom readObject() and writeObject() methods
but still calls defaultReadObject(). The field marshallers will now
be configured a little later in the game than before.
But, we're actually saving a bit of memory by not setting up those
marshallers for streamable classes that never use them. Woo.
Please let me know if this causes any space shuttle explosions or
spikes the punch at your quinceanera.

signals for each field that can be listened to individually.
From the old:
barrel.addListener(new AttributeChangeAdapter(function (event :AttributeChangedEvent) :void {
if (event.getName() == BarrelObject.MONKEY_COUNT) {
// ... cast event.getValue() and use it
}
}));
to the new:
barrel.onMonkeyCountChanged.add(function (newValue :int, oldValue :int) :void {
// ...
});
Only AttributeChangedEvent have been signalified, but I'm planning to continue with the other
ChangeListeners shortly.

accomplish what we need without misleading casts.
This will require changes to Yohoho which I shall make forthwith.

* Rename PrefixServer.Module classes to PrefixModule. They all implement guice's Module, and it's
hard to pass a class around as its interface if they share a name.

The presents-specific portions of ConnectionManager like reading Message subclasses and sending
datagrams are now in PresentsConnectionManager. PresentsServer should behave identically, except
during shutdown. Before, connections would be accepted and datagrams would be read until the OMgr
thread exited. Now, both stop as soon as the server begins its shutdown. This seems like an
improvement to me, but let me know if it causes issues and I can rework it.

It provides code generators for streamables, services and receivers, but not DObject. It uses
Apple's CFNetwork for its sockets and builds with XCode, so it's limited to OS X and iOS. It should
be straightforward to replace both to make it cross-platform.

ConnectionManager thread. Add transferAcceptedSocket for outside socket
acceptors to call. It sticks new sockets into a queue, which are then passed
to handleAcceptedSocket as part of ConnectionManager's iterate.
