split nexus connection stuff into NexusConnectionUI so it can be reused in the instance creation dialog

removed the PluginContainer* parameter from NexusInterface::instance()
 - it's a singleton, so it only needs to be given once, not every time
 - it doesn't even matter because the first time instance() is called, it creates the singleton, but the plugin container is always null
 - and setPluginContainer() is called much later from OrganizerCore with the correct value
added non functional nexus page to instance creation dialog
