Another method to check for jmeter plugins

Hi,

i came across the new way to specify jmeter plugins. I like the last approch better where i only need to add the plugin to the dependencies of the jmeter-maven-plugin. 
So i wrote a little examination of the dependencies for implementations of TestElement. 

I would appreciate it very much if you would include this into the official jmeter-maven-plugin. It would be backward compatible and still sort plugins into "lib/ext" and all other libs into "lib"
