Add some DocBlock comments to Yii sources that will improve code autocompletion in IDE

I propose to add DocBlock comments "@property <type> <$name>" for classes that have <get|set><Name> methods, that can be used as properties due to magic setters/getters in CComponent.

This will make coding with Yii little more convenient due to better code autocompletion in IDE.

Example for CController:

These comments should include description as well. Also if there is only get method then it should be @property-read.

I will accept patches adding such phpdoc. Just post these at
