Support for various JNLP tags, like <icon> and <shortcut>

[TurekBot]

I've finally got this wonderful plugin configured to create a JNLP file for my application.

I noticed that most of the elements under the <information> tag, like <offline-allowed>, and <homepage> are included by default.

Is there a way to configure the plugin to add an icon?

I've added the following to the default template,

...
#if($project.Description)
    <description>$project.Description</description>
#end
#if($icon.Href)
    <icon href="$icon.Href"/>
#end
#if($offlineAllowed)
    <offline-allowed/>
#end
...

But when I give that template to the plugin, I get
[ERROR] Failed to execute goal org.codehaus.mojo:webstart-maven-plugin:1.0-beta-7:jnlp-inline (default) on project purchase-order-arrivals: Unable to parse configuration of mojo org.codehaus.mojo:webstart-maven-plugin:1.0-beta-7:jnlp-inline for parameter icon: Cannot find 'icon' in class org.codehaus.mojo.webstart.JnlpConfig -> [Help 1]

I think I'm on the right track. I looked at the source and thought maybe it would need to be updated to support icons as well; if so, here's what I've managed so far: #51
Can anyone help?
