Title: [Fix #577] A cop for requiring no parentheses in method definitions

This change introduces enforcing a method definition style without
parentheses like this:

def columnsort array, size
end

This change also reworks the DefWithoutParentheses cop and replaces it
with MethodDefParentheses with EnforceStyle: no_parentheses

This fixed #577.
