1. Now shell can take compile script. This based on the initial patch from
Patrick Beard <pcbeard@mac.com>.
2. Using common code to read source and compiled scripts and for script
execution.

processes breakpoint hit and another breakpoint is met during event processing,
then on Linux recursive invocations of EventQueue.getNextEvent()/dispatchEvent
lead to eventual GUI deadlock. It is easy to observe when the break on function
enter is enabled and a JS function is called that is attached to an action
handler of some button. With recursive bahaviour repeated clicks lead to deeper
and deeper invocation of EventQueue.getNextEvent() and GUI deadlock on Linux.
So to improve debugger stubility I modify Dim.interrupted to ignore calls from
event thread when another invocation of Dim.interrupted already waits for GUI
result.
2. To decrease class and jar bloat I merges various implementations of Runnable
and and other interfaces to single class with switch dispatch. It saved about
6K from js.jar.
JavaSriptException now inherits from RhinoException which inherits from RuntimeException and as such it does not necessary to declare it.
Moreover, it is wrong to use it for the documentation purpose since a script can also throw EcmaError and WrappedException and a proper documentation would require to document those exceptions as well. But since almost all Rhino functions can potentially execute script code it means that wast majority of functions would bear the declarations, not only code overriding or calling explicitly Function.call/construct. And then the throw declarations would bring no information if it always would be "throws RhinoException". Thus it is better not to litter sources with the declarations at all.

Thanks!
the later is stored in the factory and not in static variables.
For compatibility an instance of ContextFactory stored in static variables
is used to provide support for old Context.addContextListener etc. API.
The static instance of the factory is also used by Context.enter to create
Context instances providing simple way to customize Context: one just need
to initialize the global static factory.
Context.call(new ContextAction() {
public Object run(Context cx) { ... }
});
or similar alternatives.
It prevents bugs with missed Context.exit and provides room for optimization of Context association with current thread and simplify implementation of safe environment for execution of untrusted applets and scripts.
In addition, Rhino now supports global SecurityController that take precedence over any per/Context controllers so the application can setup the controller once and for all.
