Beta Release v0.3.0

Added functionality:

• Added config option overrides for the command line
  • Can define in command line --option parameter or without a parameter --option for a user prompt
  • Use the --help option for more details on these options
• The directory parser can now handle full (absolute) file paths in the sample list file

Bug Fixes:

• Fixed hard crash that sometimes occurred when valid url's were given as the base_url
• Fixed hard crash when running the miniseq parser on a miseq run directory

API Changes:

• Added 400, 401, 403, and 500 to http errors we explicitly have exceptions for. (Other errors still generate generic exceptions that are handled the same way.)

Developer changes:

• Added pep8 testing with make pep8
