* net/sourceforge/jnlp/cache/ResourceTracker : (findBestUrl)
now trying GET after each error request of HEAD type. Changed and
added debug messages. (getUrlResponseCode) closing of stream
moved to separate method HttpUtils.consumeAndCloseConnectionSilently
* net/sourceforge/jnlp/util/HttpUtils.java: new file designed  for
http utils. Now contains (consumeAndCloseConnection) and
(consumeAndCloseConnectionSilently) which calls consumeAndCloseConnection
but do not rethrow exception
* netx/net/sourceforge/jnlp/util/StreamUtils.java: removed (consumeAndCloseInputStream)
now improved and moved to HttpUtils


* netx/net/sourceforge/jnlp/cache/Resource.java: added fixme to warn before wrong url comparator
* netx/net/sourceforge/jnlp/Version.java: removed useless main. Its purpose moved to new
* tests/netx/unit/net/sourceforge/jnlp/VersionTest: some small tests to version class
* tests/netx/unit/net/sourceforge/jnlp/cache/ResourceTrackerTest.java: added tests to
(getUrlResponseCode) and (findBestUrl)
* tests/netx/unit/net/sourceforge/jnlp/util/HttpUtilsTest.java: added tests for
(consumeAndCloseConnectionSilently) and (consumeAndCloseConnection)
* tests/netx/unit/net/sourceforge/jnlp/util/UrlUtilsTest: added license header
* tests/test-extensions/net/sourceforge/jnlp/ServerLauncher.java: and
* tests/test-extensions/net/sourceforge/jnlp/TinyHttpdImpl.java: added support for simulation
of not working HEAD request

Ok. I have improved the message.

Ok, I have at the end added unittests to all methods I have touched. Imho it is worthy - but no more 
bugs was found this time :)

If you do not like the tests,please let me push the fix and discuss the tests separately.

Also do you mind you can check - Re: [rfc] [icedtea-web] renaming Messages_cs_CZ to Messages_cs (was 
Re:ITW tranlsation) ? It should just need and experience yes/now. The code change itself should be 
very simple then (just renaming the file..)
