As Widget's already denote an abstract concept, the name
'AbstractWidget' is redundant. Also this class didn't do anything except
fetching a view via a singleton (which is now injected into the render method)
and bypassing the PHP class properties by creating a 'properties' array which is
filled with magic getters and setters (which now are simply php class properties)
Further changes:
- toString is removed, as this incorporated a lot of
application logic which would cause unrecoverable
errors when throwing exceptions
- renderToHtml is now just render and the view dependency must be
passed, as a widget shouldn't be responsible for getting
view instance (this means that <?= $this->tabs ?> is now
<?= $this->tabs->render($this); ?> in the templates
- Controllers don't have $this->widget anymore as Widgets are
directly instanciated with their class, allowing better code completion
and avoiding hidden dependencies, also Widget::create is now removed
in favor of direct instanciation.
