Crash: KeyError: 'podcast-directory'

[willemw12]

On Arch Linux (https://aur.archlinux.org/packages/podfox-git/), podfox crashes:

$ podfox feeds                                               
Traceback (most recent call last):
  File "/usr/bin/podfox", line 11, in <module>

A way to fix this is to declare CONFIGURATION global:

def main():
...
        try:
            global CONFIGURATION
            CONFIGURATION = json.load(conf_file)

It is patched now for Arch Linux, however, other platforms or distros may also have this issue.
