Subject: [PATCH] minifiers support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Quick and dirty workaround in order to get rid of ‘new’ and ‘class’
javascript reserved keywords which prevent most used compressors to
work. It would be better to change property names.
