Caveat emptor:
PA has a few bugs, that will first cause the 'Check' link on the plugin management page do nothing.
When you fix that, you have to either manually change the plugin state in plugin_config table,
or patch the api_plugin_check_config function, becuse the plugin will be stuck in 'Awaiting...' state.
