Handle unicode paths

[lhagan]

phoshare does not handle paths containing unicode characters. Potential fixes suggested by Michel Boudinot:

1. set the default encoding to utf-8, using the kludge of adding import sys; reload(sys); sys.setdefaultencoding(‘utf-8’) in the __init__.py file.
   or
2. leaving the default encoding alone, (actually, it is ascii), implement a UnicodeConfigParser() function (http://sysmagazine.com/posts/119405/) and I use it in place of RawConfigParser() in the save() function.
