Add node

Add a new node address to the explorer: the node will serve as data source for it. This information will be stored in the browser and will only be visible to you. You can add your local node by specifying the private IP (use `ipconfig` command on Windows or `ifconfig` on Linux/MacOS/Android or get it from Syrius wallet -> Info -> About -> Local IP address) of the device where the node is running, e.g. http://192.168.0.100:35997
