[pygame] Color slice problem with Python 3

[Lenard Lindstrom <len-l@xxxxxxxxx>]

Hi,

The Color unit test is failing for Python 3.1:

======================================================================
ERROR: ColorTypeTest.test_slice
----------------------------------------------------------------------
Traceback (most recent call last):
 File 
"/home/lenard/.local/lib/python3.1/site-packages/pygame/tests/color_test.py", 
line 225, in test_slice
   self.assertEquals((1,2,3,4), c[:])
TypeError: sequence index must be integer, not 'slice'
