[Kde-java] Some questions - long - KScribble in java

[Richard Dale]

I've checked in Emond's tutorials and example app into 
kdebindings/qtjava/javalib/tutorials and 
kdebindings/qtjava/javalib/examples/application.

And I've checked in Kenneth's KScribble into 
kdebindings/kdejava/koala/examples/kscribble.

Both work fine with Qt 3/KDE 3

Added as static methods KIconLoader.BarIcon(), KIconLoader.BarIconSet() etc

I added QObject.i18n() as a synonym for tr().

KConfig.readListEntry() and writeListEntry() have now been fixed.

The method KPixmap.load() is correct and works fine - format is 'const char *' 
in C++ which should become a java.lang.String.

Here are some other fixes which came out of testing KScribble with the 
Qt3/KDE3 bindings:

	- QPaintDevice - added missing bitBlt() methods

	- QPopupMenu - added missing insertItem() methods

	- Added missing QPointArray(int) constructor

	- QtSupport - Added extra default parameter to C++ -> java array
           conversions,so an existing java array can be used as a target.

	- KAccel - Fixed java slot connections

	- JNI function name link problems in KURL.directory() and KImageIO.pattern() 
           fixed.

	- Added KMainWindow.memberList() method.

Drag and drop don't work with C++ either with my version of kdelibs, so I 
don't think there is anything wrong with the java version.

Apart from that, it now looks and behaves identically to the original C++ one 
in every way - a really good test.
