Checking for pin direction

[GoogleCodeExporter]

I'm wondering if a way to check whether pins are currently set as inputs or 
outputs can be implemented.

It'd be useful so we can toggle the direction of a pin, i.e., for 
bi-directional I/Os, or logging actual pin directions.

There is a GPIO.gpio_function(gpio) function - gpio must be a BCM number at the 
moment.  The details of this are missing from documentation on the wiki of this 
project so I will have to add it.

Tasks required to fix this issue:
- add documentation of gpio_function()
- accept BOARD numbers depending on current mode

Altered gpio_function() to accept BOARD numbers as well as GPIO numbers, 
depending on current mode

Made return values of gpio_function() more descriptive (INPUT, OUTPUT, SPI, 
I2C, PWM, SERIAL, UNKNOWN)

Still needs documenting in wiki

Fixed in 0.5.4
Documentation is in the RPi.GPIO project wiki (now on Sourceforge)
