Allow hash when loading local url (file://)

[GoogleCodeExporter]

Currently passing hashes along with url does not work. A fix would be required 
in utils.pyx in the GetNavigateUrl() function, urllib_pathname2url() should not 
be called for the hash url. The original url is modified to support filenames 
with chinese characters, see the code:
