Download JAR files tagged by usurped with all dependencies

Usurped versions of the plugin.

This was usurped by IB. Follows is the original stuff:: This is a plugin meant to help maven user to download different files on different protocol in part of maven build. For the first implementation, there will only be a goal that will help downloading a maven artifact from the command line. Future version of the plugin could include web download, ftp download, scp download and so on.

Usurped Modello plugin, generally depending on the existing plugin tree to work properly. This particular one adds 2 generators that produce reflection-based reading so that the lack of java getters doesn't break generation. Sorry if the original contriubutors list isn't generated. A given version of this code will be based on some version of modello with some additional 4th number like ".0" appended to the version.
