Bugs fixed in V0.2-1

There were a few bugs in the initial release of Version 0.2 which were fixed in the current bug fix release. Here is the list of them:

• When using the methods HTTPConnection.Head(file, form_data), HTTPConnection.Head(file, form_data, hdrs), HTTPConnection.Get(file, form_data) and HTTPConnection.Get(file, form_data, hdrs) the form_data was URL-encoded twice instead of once.
• If the first request returned with a status code of 4xx or 5xx and the server is doing HTTP/1.0 then the request threw an EOFException. This happens for instance when the server requests authorization, or when the file doesn't exists, or if the server does not accept the request method.
• This one is not really a bug, but may be a nuisance: a thread is started in the HTTPClient to handle certain timeouts. In some cases this thread was suspended and never killed. The main effect was that some applications would seem to hang at the end, as the VM waits for all threads to die before exiting. Note though that if you start any windows stuff (this includes the authorization box popup in the HTTPClient) then there will always be a few threads hanging around when it's time to end. One way of forcing the program to exit is to call System.exit() when it's time to end.
• Under certain circumstances if an IOException occured during a request then this Exception was not properly thrown; this resulted in a NullPointerError in StreamDemultiplexor.read() shortly afterwards.

Thanx to the following people for finding and helping me fix these bugs: Gil Bregman, Martin Heinzl, Akkana Peck, Olivier Baujard.
