SelectedIcon not localized

Hi,

I am using the localizer not only for text but also for resources,
like icons.

So my XML contains something like:

   <label icon="printjob.icon.large"/>

and the .properties file:

    printjob.icon.large=res/icons/PrintJob2.gif

ok, this works - but something like

   <button selectedicon="printjob.icon"/>

does not work because "selectedicon" is not in the parsers
LOCALIZED_ATTRIBUTES vector and will not be translated. The same
problem exists when you define a custom tag with attributes that
should be translated and are not in the parsers vector:

   <actionmenuitem deselectedicon="printjob.icon.gray" selectedicon="printjob.icon"/>

here both icons will not be translated.

As far as I can see there is no way for a client to add strings to
the parsers LOCALIZED_ATTRIBUTES. LOCALIZED_ATTRIBUTES is defined as
public static final in Parser.java but there is no way to get the
parser instance from the SwingEngine.
I would suggest to add a method like addLocalizedAttribute(String).

Any comments?
