F/3.0 bake improvements 5319

Add two bake improvements:

Add NotFoundException to Controller view and edit methods
Set variables using compact at Controller view method
@markstory I am guessing this ties into [the automagic it's-a-select](https://github.com/cakephp/cakephp/blob/3.0/src/View/Helper/FormHelper.php#L1132-L1135) detection - I thought that had been removed in 3.0 in favor of being more explicit.
