Bug 119404 – Give the error object's stack property accessor attributes.

[Chris Curtis]

Treat the stack property like an accessor to match the functionality of Chrome error objects.

Something to note: This does NOT affect the inspector's console because it reads from the vm->exceptionStack, not the error object's stack

Extra "allows"

Why did you use the Accessor property attribute instead of None?

Accessor claims to be for getters and setters:

    Accessor     = 1 << 5,  // property is a getter/setter

That doesn't seem right here.

Changed the stack attribute to have no attributes. I was thinking of that the stack was a data member of the error object, which is why I gave it the accessor attribute, but giving it no attributes makes more sense.
