* Do not use RssThred
- All timer tasks are being run in a thread of their own, created by the java.util.Timer. Hence, there's no need to be executing a new thread
* Renamded recupFlux() to retrieveFlow()
- nothing but English in source code!
* Added an OperationFailedException to retrieveFlow()
- we need to have some kind of indication if retrieving a flow fails so that we could act accordingly (e.g. not add a contact to the contact list)
* The reader should be created with a URL object and not an unparsed string.
- URL objects must be created as early as possible (e.g. at the time a contact is added to the contact list) so that we could parse and test the syntax of the URL and ignore the contact if we encounter any problems.
* Made the sortItems() method private
- seems that there's no one else using it.
* Made sortItems use Arrays.sort()
- thought it would be better this way rather than let it implement the sort itself. I've therefore also added a comparatator class.
* ReReversed sort order for RSS posts.
- given the way SC wokrs and what it is used for, the user is most likely to only be seeing the last messages being printed out. In the meantime, the msgs that a user would be most likely to be looking for are the newest, so it would be better if they were printed last.
* Removed calls to System.out.println()
- we should be using net.java.sip.communicator.util.Logger instead.
* Removed the deliverAuthentication() method
- seems like Gibberish residue so I decided to drop it. I don't think we handle or need authorizations in RSS do we?
* Remove the createVolatileContact() method.
- we don't really have that for RSS
* Remove the getNonPersistentGroup() method
- unused
* Remove the findProviderForRssID() method
- unused. (Gibberish residue?)
