Must be run within working directory

[vrillusions]

If called from anywhere else it can't find the config file and complains:

cd ~
projects/simplenote-cli/sn.py
ERROR, UNEXPECTED EXCEPTION
No section: 'simplenote'
Traceback (most recent call last):
  File "projects/simplenote-cli/sn.py", line 123, in <module>
    main()
  File "projects/simplenote-cli/sn.py", line 61, in main
    email = config.get('simplenote', 'email')
  File "/usr/lib/python2.6/ConfigParser.py", line 531, in get
    raise NoSectionError(section)
NoSectionError: No section: 'simplenote'

Just need to make the default be the full path to the config file.
