Makefile.am: Move beans and applet classes to awt_java_source_files.

2000-08-09  Bryce McKinlay  <bryce@albatross.co.nz>

	* Makefile.am: Move beans and applet classes to
	awt_java_source_files.
	* Makefile.in: Rebuilt.
	* java/awt/Color.java (getTransparency): New method.
	* java/awt/Component.java: Various updates.
	* java/awt/Container.java (removeNotify): Call super.removeNotify()
	after dealing with children.
	* java/awt/Toolkit.java (changeSupport): Renamed from pcsupport.
	* java/awt/Window.java: Various new methods and updates.
	* java/awt/color/ICC_Profile.java (getNumComponents): Cast profileID
	to int for switch.
	* java/awt/event/KeyEvent.java (paramString): Initialize `r'.
	* java/awt/event/WindowEvent.java (paramString): Ditto.
	* java/awt/geom/Dimension2D.java (clone): Wrap super call with
	try/catch block.
	* java/awt/geom/Point2D.java (clone): Ditto.
	* java/awt/geom/RectangularShape.java (clone): Ditto.
	* java/awt/image/ColorModel.java (bits, cspace, transparency,
	hasAlpha, isAlphaPremultiplied): Make package-private, not private.
