Implements Yii::$classMap to improve performance of YiiBase::autoload in real world scenarios. The intention is to get the minimum appserver request from 90ms to ~60ms.

Also introduces CiiClassMapCommand for generating this file. This command needs to be run anytime a new component, controller, or model is generated for CiiBase.
Merge branch '1.9.0' of github.com:/charlesportwoodii/CiiMS into 1.9.0
