Changed the server to use the external util package. Quite a minor change,
but does affect a lot of files.

i-scream is now licensed under the GPL. I've added the GPL headers to every
source file, and put a full copy of the license in the appropriate places.
I think I've covered everything. This is going to be a mad commit ;)

Split the CORBA side of the filter in two. The Filter interface still does
the receiving of data, just like it used to. This can optionally be turned
off in the configuration if required. The new interface, FilterInfo, is
used to provide information (host and ports) to other parts of the server
about the Filter - namely the FilterManager. This split has been done so
that the data receiving part of the Filter can be turned off, without
breaking the FilterManager.

Major change in the java package naming. This has been held off for some time
now, but it really needed doing. The future packaging of all i-scream products
will be;

uk.org.iscream.<product>.<subpart>.*

In the case of the central monitoring system server this will be;

uk.org.iscream.cms.server.*

The whole server has been changed to follow this structure, and tested to a
smallish extent. Further changes in other parts of the CMS will follow.

Fixed a long standing problem with the Filter not returning it's own host
address (fqdn) on windows machines. It's a bit of a workaround, but at least it
works :)

A structural change to the Filter.

The old setup looked like this;

UDPReader ------> FilterThread (thread) --> (parent)
TCPReader ------> FilterThread (thread) --> (parent)
FilterServant --> FilterThread (thread) --> (parent)

Seeing this from a threaded point of view, each time a packet came in (through
whatever means - UDP, TCP or CORBA), a FilterThread instance was created to
deal with it. If the link to the parent was slow this resulting in a build-up
of FilterThreads all waiting to talk to the parent - and there is only one
actual parent object, with a synchronised thread, so they have to queue up
anyway.

As a result of this, the following change has been made.

UDPReader -------\
TCPReader ----------> Queue (single) >-- FilterThread --> (parent)
FilterServant ---/

In this setup, each of the three objects that generate packets only see the
single instance of a Queue. They all add their data to this Queue, and then
carry on with the task of listening. The FilterThread (having it's role changed
slightly) now acts as a consumer of the Queue, in that it grabs data from the
Queue and deals with passing it on to the parent.

This setup should be more efficient in the long run, especially under a high
load situation. The only problem could be the Queue growing to an unlimited
size, but this is a Queue design issue.

Changed all classes so that references to the Logger and ConfigurationManager
are no longer passed around between classes. All of the classes now utilise
the new ReferenceManager, which makes life much easier.
Also tidied everything so that they all use the same conventions for attributes,
namely the _ prefix to the name.
