Add support for exploded .less stylesheets (basically, include less.js when .less files
are included in the page). This inclusion needs 3 steps:
 1) include the .less files as .css, that way Wro4J will handle them
 2) include the tag '<wro:optionalScript />' at the end of the header AFTER the .less
    stylesheets, that's were less.js will be inserted if needed
 3) define the path to 'less.js' in your web.xml using the context parameter
    'com.orange.wro.less.path'
