Environment loading error

[hazmat345]

• Yapcon version: 0.3.0
• Python version: 3.6
• Operating System: Centos 7

Config loading breaks after upgrading from 0.2.4 to 0.3.0.

This is the call that's breaking:

spec.load_config(cli_args, 'ENVIRONMENT', bootstrap=True)

And the output:

brew_view/__init__.py:41: in setup_brew_view
    config = bg_utils.load_application_config(spec, cli_args)
../bg-utils/bg_utils/__init__.py:132: in load_application_config
    temp_config = spec.load_config(*config_sources, bootstrap=True)

Can confirm. Will release 0.3.1 tonight.

Can confirm that 0.3.1 fixes this. Thanks!
