[Image-SIG] Patch for ImageFont.py from PIL 1.0B1

[Barry Scott]

In ImageFont.py the function load_path uses "except:" this catches
too many errors. I suggest this version of the function:

def load_path(filename):
    "Load a font file, searching along the Python path."
    for dir in sys.path:
	 try:
	    return load(os.path.join(dir, filename))
	 except IOError:
	    pass
    raise IOError, "cannot find font file"

I found this out because I upgraded FreeBSD from 2.2.8 to 3.1 and
now get the following error that I'm assuming means I must recompile
Python and PIL for the new ELF image format of FreeBSD 3.X.
