Applied the patch provided at https://jira.codehaus.org/browse/MJSIMP-8
Added handler for "min" artifacts. This uses the idea that a min file may be attached to the artifact so that regeneration of the min file is not necessary (i.e. for 3rd party libraries that provide one)
Added ability to intelligently handle the "min" classifier (mutually exclude, unless specified otherwise) and determine which to use (removing one or the other)
