Improve localization/message-customization

[GoogleCodeExporter]

The support for localization (messages-customization per-se) isn't comfortable 
enought.

I'm migrating from GWT-Ext [that was quick & easy]:

 userName.setAllowBlank(false);
 userName.setBlankText(messages.getDefaultBlankField());

now

 userName.setRequired(true); // GOOD: more readable

...
...
BUT to set a customized error message i've found only this option:
...

 RequiredIfValidator reqValidator = new RequiredIfValidator();
 reqValidator.setExpression( new RequiredIfFunction() {
    public boolean execute(FormItem formItem, Object value) {
        return true;
    }
 });

 reqValidator.setErrorMessage(messages.getDefaultBlankField());
 userName.setValidators(reqValidator);

...Frankly too much...

The option (more understandable)

 userName.setRequiredMessage("New Req Msg");

[not exist]

...and the last

 userName.setProperty("requiredField", "New Req Msg");

...Is not working...
