array fields are not syntax highlighted

Considering the following code:

// Here type `Foo` is green
contract Foo {
    // Same as here for type `string` 
    string first;
    // But `Bar` type is white
    Bar[] second;
    // And here `Bar` type is blue
    constructor(Bar[] bar) public {
      // Here `Bar` type is white again
      Bar[] x = new Bar[](10);
    }
}

This is how it is highlighted in editor today:

I suggest unifying how type names are colorized, as otherwise they indicate different semantics to readers.
