The following new attribute added on the inputRichText component, to define the custom configuration path.
-customConfigPath

The configuration of the FCKEditor can be changed using the js file defined by the above path, relative to the web root.

In order to get the custom toolbar, there are two steps are involved.

1- Define a toolbarset into the JS file, and place it into the web app.(e.g.)

web_application_root/js/my_config.js
FCKConfig.ToolbarSets["MyToolbar"] = [['Bold','Italic', 'Underline'], ['Save']] ;

2- Define the customConfigPath and the toolbar name on the inputRichText component (e.g.)
<ice:inputRichText customConfigPath="js/my_config.js" toolbar="MyToolbar" />

An initial version of this is implemented by ICE-2721.

In order to define the custom toolbar, the following snippet needs to be put inside the config.js.

FCKConfig.ToolbarSets['custom'] = [
['item1'],
['item2'],
['item3', 'item4]
] ;

To server the FCKeditor resources we use a zip file (fckeditor.zip). So its not straight to take above snippet as string parameter and manipulate the config.js inside the zip and serve it.

I thought after loading the FCKeditor API, the "FCKconfig" will be available into the javascript context as a public variable, but when I tried it, I didn't find it.
