errors abound

Breaking: removed no-errors rule. Instead, each individual rule will report parse errors in the target imported file, if encountered.

#90: Added {commonjs: [bool], amd: [bool]} option object to no-unresolved. If set true, will attempt to resolve module paths for CommonJS require and AMD define + require in a limited set of cases. Not nearly so smart as Webpack, but smart enough to be useful. (hopefully.) Thanks @mctep for changing my mind on this. 😁

#94: Dependency parser will infer 'jsx' plugin if using default Babylon and jsx is asserted in the ecmaFeatures. Thanks @jameslnewell for bringing this up.

#88: un-smarted no-require. It will now report on all require statements, everywhere, regardless of target.
