Feedback on config

[hayd]

At the moment it looks at default (home config) then updates with local configs (.pep8 etc) then updates with passed in arguments. See #71.

Was hoping for feedback before pushing release...

Concerns:

• This may raise if there are bad config files. Personally I think this is a good thing.
• If you are using a projects config perhaps you don't want to dirty it with your own? (currently if configs are not set locally then defaults are from the user's config). I'm unsure about this behaviour.

Thinking of changing API slightly (but will match whatever autopep8 decides), to have --global-config and --ignore-local-config for the following behaviour:

• if --global-config use this path as global_config
• else set global_config to DEFAULT_CONFIG
• update parser with global_config (if file is missing this does nothing)
• if not passed --ignore-local-config then update parser with local config (found with parent-tail in autopep8, just looking in root dir here)
• update with passed in arguments
