Added integration with SilkSpawners for mob spawners. When mob spawners are auctioned it shows the mob spawner's type. Additionally added a config value to just allow spawners that are renamed instead of all items if you wish to use that feature. Also as always before any update make sure to backup your config.

The plugin that I added integration to is the plugin here: http://dev.bukkit.org/bukkit-plugins/silkspawners/
