[Numpy-discussion] Release tomorrow

[Travis Oliphant]

I just made some changes to the system_info file to parse site.cfg from 
the three standard locations (in order)

1) System-wide (the location of numpy/distutils/system_info.py)
2) Users HOME directory
3) Current working directory

I'm assuming the config parser will update the appropriate sections as 
later files are read.

I'd like to make a release tomorrow but would like a code-review on my 
changes in this section before hand.  If somebody who uses site.cfg 
could try out the SVN version and see if it works as expected.  That 
would be great.
