Changes to Bamboo's configuration UI require the ConfigurablePlugin

In Bamboo 2.0, any plug-in that adds to Bamboo's configuration user interface must also implement com.atlassian.bamboo.v2.build.ConfigurablePlugin. This is most easily achieved by extending com.atlassian.bamboo.v2.build.BaseConfigurablePlugin.

If you do not implement the ConfigurablePlugin, the user interface for your custom plugin may not display correctly (even when the plugin works correctly otherwise).
