Add the option to call a model method when generating list data in valueEx

[GoogleCodeExporter]

I'm hoping to be able to call a model method before outputting a string for a 
dropdown list:
echo 
$form->dropDownList($model,'id',GxHtml::listDataEx($clients,'id','nameForList'))
;

What do you see instead?
I get an error stating that nameForList isn't defined for my model (I knew that 
:-)

What version of giix are you using?
1.9.1

What is your stack (operating system, web server, DBMS, PHP version)?
Ubuntu 10.10, MySQL, PHP 5.2

What version of the Yii Framework are you using?
HEAD

I've pasted in a patch here for valueEx.  Seems like it could add just an 
additional bit of ease to using GiiX.  Thanks for all the work on it, I use it 
a lot these days!

Is this a feature request?
Maybe you should post on the forum topic for giix:

A suggestion: you can try calling the method directly instead of passing its 
name as a string.
