Make wro xml and properties files optional when using maven-wro4j-plugin

I'm always annoyed having to create wro.properties and wro.xml when using 
maven-wro4j-plugin. Ideally, all that configuration could be done directly in 
the maven-wro4j-plugin <configuration>

You'd have something like : 

<configuration>
  <targetGroups>bootstrap</targetGroups>
  <cssDestinationFolder>${project.build.directory}/${project.build.finalName}/css/</cssDestinationFolder>
  <jsDestinationFolder>${project.build.directory}/${project.build.finalName}/js/</jsDestinationFolder>
  <wroManagerFactory>ro.isdc.wro.maven.plugin.manager.factory.ConfigurableWroManagerFactory</wroManagerFactory>
  <preProcessors>cssImport,semicolonAppender</preProcessors>
  <postProcessors>lessCss,cssMinJawr</postProcessors>
  <groups>
   <group name="bootstrap">
    <css>/less/bootstrap.less</css>
    <js>/js/bootstrap-transition.js</js>
    <js>/js/bootstrap-alert.js</js>
    <js>/js/bootstrap-modal.js</js>
    <js>/js/bootstrap-dropdown.js</js>
    <js>/js/bootstrap-scrollspy.js</js>
    <js>/js/bootstrap-tab.js</js>
    <js>/js/bootstrap-tooltip.js</js>
    <js>/js/bootstrap-popover.js</js>
    <js>/js/bootstrap-button.js</js>
    <js>/js/bootstrap-collapse.js</js>
    <js>/js/bootstrap-carousel.js</js>
    <js>/js/bootstrap-typeahead.js</js>
   </group> 
  </groups>
</configuration>

plugin configuration would take precedence over config files by default.
