Make folders2flickr work with Python 3

[ikwyl6]

When I run the script I get this:

$ ./folders2flickr File "./folders2flickr", line 9 except IOError, ex: ^ SyntaxError: invalid syntax
Where the pointer is located under the comma after IOError.

Using python: Python 3.4.1

That's because it has not been ported to Python 3 yet. The first line has "#!/usr/bin/env python" so should pick up the default python 2 in the path, it's unusual to have that pointing to python3.

I'll change the title of the issue to reflect the real problem here... but it's a biggie.
