Not able to upload file

[davidhrbac]

It seems to me that Ghost.py is not able to upload the file. The code bellow does not work:

g.set_field_value('input[name=cert_file]', '/tmp/a')
page, resources = g.call('form','submit', expect_loading=True)

This issue is connected to #202. I cant confirm that all the tests are OK but the set_field_value_simple_file_field.
