Persistent Application Config Params

Hey Yii friends,

I wrote a small extension for yii initially and now for yii2 to store config params in database, with the possibility to edit the values from a form without changing the code.

As a bonus, if you use a cache component, the values are stored there for fast operation.

Unfortunately I cannot upload it to the extension page, maybe somebody can tell me what to do for that.

Happy codding!
