Catch a lot of old URL's and update them. Also remove a couple of old files that aren't used.
Added URL to GPL headers.
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 ;)
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.
The whole server package structure has been changed. Old Package: uk.ac.ukc.iscream.* New Package: uk.org.iscream.*
The getDescription was not working. It has now been abstracted, and thus we must implement it, which we do. Somehow missed the SSH checker when doing the abstract class. Also, the Telnet checker was not returning. Now it just checks it can connect.
Made an abstract skeleton class for the service checks. They all do very similar things, so it seemed worth putting all the behaviour in one place. This also has another advantage, namely that service checks are now much quicker to produce, and that in the future the checks could even be moved to a general checker that reads from the configuration.
"Failure" messages (where an exception has been thrown) were being sent with a 0 status, which actually means ok. Opps.
Added a selection of new Service Checks. These are basic, and only get back a simple line from the server. This could probably better be done with an abstract class. Actually, it needs to be considered whether it matters what is sent back, because maybe we just care about the fact a service exists.
