That way, nobody has to worry about null StackFrames in the SourceWindow.

	* StackFactory.java (createStackFrame): Catch Exceptions coming out of
	StackTraceCreator, and return an empty StackFrame instead of null. Fixes
	#3723.
	* StackFrame.java (StackFrame): New constructor, taking a Task. Used to 
	create an empty StackFrame.
	(getMethodName): If the method name is null, return an empty String 
	instead.

	* CurrentStackView.java (buildTree): Won't get null StackFrames
	anymore, removed redundancies. Compare Tasks using their TID.
	* SourceBuffer.java (highlightLine): Return before doing anything
	if the scope of this Buffer has no source. If the incoming StackFrame
	has no debuginfo, try and find a frame in the stack that does.
	* SourceWindow.java (populateStackBrowser): Cleaned up, removed
	redundant checks. Fixes #3723.
