a few changes to make plugin development easier:

1. copy statements in buildplugin macro use the overwrite value from ${overwrite}, default is true
2. there is a target plugin that will build the plugin that has the name ${plugin}
3. run target does not depend on jar, instead displays a message mentioning that jar should have been already run, this increases the startime of the target significantly
