If the line never changes during execution, the line step won't actually finish.

	* SourceWindow.java (lineLoopCount): Added. Keeps track of the
	number of instructions executed by each thread.
	(stepIn): If lineLoopCount reaches a certain level, we should assume
	that the line just won't change, and re-block everything.
	(updateShownStackFrame): If the selected frame has line number equal
	to zero, don't do anything.
