Add support for new shorter API calls. I'll outline these in the weekly blog post, but to summarize: you can now use any API variable as a function, i.e. `$body = $page('body'); $products = $pages('template=product'); $field = $fields('title');` and so on. If the API variables aren't locally scoped, you can just prepend a `wire()` or `$this->wire()` call to ie, i.e. `wire()->pages('template=product'); or $this->wire()->fields('title');`
