Description
Most (probably not all) defined built-in handlers can be removed from the many example and test solrconfig.xml's in Solr's source tree. See ImplicitPlugins.java for details. Handlers such as /admin/ping, /admin/luke, /admin/system, ... and so on are now implicitly defined. Removing these from the configs that users clone will (c)lean it up a lot.
lotsa minuses! removed most (not all, there were some non-default definitions in use) of the plugins from solrconfig's that are implicitly defined in ImplicitPlugins.java. Needs thorough testing - locally all seems fine currently. I'm running more tests as I upload this patch.
