refactor.

Rename externalPlugin to apiPlugin Rename bundle to app Move js, css, menuItem and staticRoot to be properties os App Add "app" field to panel, datasource and api plugin models. If populated then the plugin is only enabled if the specific app is enabled for the Org. If app is "", then the plugin is enabled for all orgs and can't be disabled.
