support for yii-bootstrap widget syntax

[schmunk42]

In order to maintain backward-compatibility and making transitions easier, it would be nice, if yiistrap would support "ye olde widget syntax", like $this->widget('TbButton').

Would you consider adding widgets to yiistrap, which you may have to import in your app to activate or should we create a separate package for this?

I would prefer to have this as a separate package to keep the code base of yiistrap to the minimum.
