Fails when using File backend

This must be something trivial, but I dont do python so this should be trivial for you ;)

$ ./vSPCServer -f /tmp/foo
Traceback (most recent call last):
  File "./vSPCServer", line 129, in <module>
    (options, args) = parser.parse_args()
  File "/usr/lib64/python2.6/optparse.py", line 1394, in parse_args

Okay I just tracked down the problem. It seems the default type is set to None. Adding type='string' to the parser.add_option call solves the problem

Fix is included in https://github.com/isnotajoke/vSPC.py/pull/13
along with other patch that allows one to change listening interfaces (instead of *)

Sweet, thanks for the report & patch. I should have time to take a look at it (and your other changes) this weekend.

Your fix looks solid, and I merged it into master. Thanks!
