UNC Paths on Windows / Custom Paths entry in administration webui

Hi guys,

Nice to see that this project is not dead and still a fully functional lightweight chunky server - certainly compared to my heavily customized ComicStreamer !

Two quick ones:

(1) Please allow entry of UNC / Custom paths from the admin webui, could not found it and had to shutdown the server to add those manually in the preferences.json 

(2) Please put a restart server directly in the admin webui, currently you have to get back to the local UI if you started it or fuddle with the config to make that happen
