TwICE

Push syndication has been implemented.
Subscription states are now sent, updated, and
honored. Each subscription now has its own target
URL. A payload's ice-sender will now contain the
sender's "listener" URL in the location attribute.
The code was refactored. The required
subscription-id attribute was added to
ice-package. A problem with name loading when
restoring subscribers on the syndicator side was
fixed. A problem in which catalogs returned from
syndicators improperly returned the listener URL
as the catalog URL has been fixed.

Catalogs and automatic subscriptions have been established in this release, and the code was refactored. There were bugfixes in the subscription contents, for the fact that pinging the syndicator using an unknown subscriber id did not return a 405 error (unknown subscriber id), and for the request identifiers that were being improperly generated. An attribute with a null value in an XML NamedAttribute would cause a NullPointerException; this has also been fixed.

New JUnit tests were added. Javadocs were written
for all code. Confirmation requests are now
confirmed, using the new ConfirmationPayload
class. A bug which caused an error code to be
prepended as text to all contents returned by
syndicator even when there was no error was fixed.
A problem in which syndicator would return error
407 (Unrecognized operation) instead of contents
was fixed.
