pyexiv2 can not open files with accents in filename on windows

[Rob Wallace]

Code To produce bug:

# -*- coding: UTF-8 -*-
import pyexiv2

filename = u'û.jpg'

image = pyexiv2.Image(filename)
image.readMetadata()
print image.getComment()

Expected result:
 Image JPEG comment printed

Actual Result:
Traceback (most recent call last):
  File "accent_test.py", line 7, in <module>
    image = pyexiv2.Image(filename)
  File "C:\Python25\lib\site-packages\pyexiv2.py", line 397, in __init__
    libpyexiv2.Image.__init__(self, filename)
IOError: ├╗.jpg: Failed to open the data source: No such file or directory (2)

Fix:
Instead of using utf-8 encoding for the filename use the system file system coding as per the attached patch, this has been tested on both Windows and Linux.

Thanks for the patch Rob, I'll make sure it lands into 0.2.
