raise the Python exception instead of JSError

[GoogleCodeExporter]

What steps will reproduce the problem?
import PyV8

class TestException(Exception):
    def __init__(self):
        pass

    def __str__(self):
        return "test exception"

class Global(PyV8.JSClass):

    def __init__(self):

        pass

    def testExceptions(self):
        raise TestException()

ctx = PyV8.JSContext(Global())
ctx.enter()
ctx.eval("""testExceptions()""") 

What is the expected output? What do you see instead?

pyv8 should raise the Python exception instead of JSError

Traceback (most recent call last):
    ctx.eval("""testExceptions()""")
PyV8.JSError: JSError: Error (  @ 1 : 0 )  -> testExceptions()

• Changed state: Fixed

The current implementation may introduce a slight memory leak, because pyv8 
must trace the Python exception in the Javascript exception, if the JS 
exception was eaten by JS code, those Python exception may not be collected. 
Because I can't find any way to trace the lifecycle of Javascript object.
