Allow input(gpio) when GPIO has been set up as OUTPUT

[GoogleCodeExporter]

I've just changed the condition in py_gpio.c:verify_input, line 139 :
[code]
    if ((gpio_direction[*gpio] != INPUT) && (gpio_direction[*gpio] != OUTPUT))
    {
        PyErr_SetString(WrongDirectionException, "The GPIO channel has not been set up");
        return 0;
    }
[/code]

So we can directly the output state using input function :

>>> import RPi.GPIO as g
>>> g.setmode(g.BCM)
>>> g.setup(7, g.OUT)
>>> g.input(7)
False
>>> g.output(7, 1)
>>> g.input(7)
True
>>> g.output(7, 0)
>>> g.input(7)
False

I see what you mean now when you reported this by email.  I now see why this 
would be very useful for WebIOPi!  I'll see what I can do...
