Remove passing view options as a function

[paulfalgout]

Resolves #2229

Essentially Marionette.Views allow you to pass in options as a function like:

var optionsFunc = function(){
  return {
    foo: 'bar'
  };
};
var myView = new Marionette.View(optionsFunc);

For one thing it is inconsistent with option handling on anything that is not a view: https://github.com/marionettejs/backbone.marionette/blob/master/src/object.js#L7

And another thing.. it is really pretty pointless and probably promotes bad patterns.

Also it was a largely broken "feature" for most of its existence.
