No way to get stack trace from javascript TypeError or ReferenceError #178

Run something like the following:

import PyV8
c = PyV8.JSContext()
c.enter()
c.eval("function f(){foo = null; foo.bar();};")
c.eval("f()")

The resulting exception shows the line of the error, but there appears to be no 
way to get the full stack trace (like there would be if the code was something 
like 'throw Error()')

It's a design issue, because the build-in Javascript error will be mapping to 
build-in Python exception

static struct {
  const char *name;
  PyObject *type;
} SupportErrors[] = {
  { "RangeError",     ::PyExc_IndexError },
  { "ReferenceError", ::PyExc_ReferenceError },
  { "SyntaxError",    ::PyExc_SyntaxError },
  { "TypeError",      ::PyExc_TypeError }
};

So, after translate the exception, the stack trace will be lost in the current 
implementation.

I will work on it later, maybe add it to Exception object
