Firebug log default collapsed

The auto-expanded firebug-log can be annoying when you want to use the javascript console.

It can easily be changed to auto-collapse the log when opening the window like this:

framework/views/log-firebug.php

console.group("Application Log"); => console.groupCollapsed("Application Log");

What do you think? Maybe this should be the default option?

Sounds good. Please add it to issue tracker at code.google.com/p/yii.
