Input list redux

[jgreben]

Fixes #259

• Combined reducer for list and literal components
• Changes InputList component to dispatch state to reducer action
• Tests for modified component and list reducer
• bumps up max-warnings to allow for security/detect-object-injection, but this is safe because user cannot inject anything in place of var i needed to parse the json to create the selection list

Overall, looks good to me,. Added suggestion to remove error about security/detect-object-injection warning.
