Backup Chrome extension configuration

Hello,

I reinstall the OS on my PC a few times per year, and every time I need to reconfigure the Join Chrome Extension on the same computer and it also loses the device ID:

- Action reconfiguration can take a while (finding the right icon URL ...)

- Losing the device ID messes up with Tasker automations, Join Actions, IFTTT commands using the Join API

I think there should be an option to backup the chrome extension configuration; at least a local XML backup file that we could restore when we reinstall the extension. The interface should ask the user to load the local backup file, and ask which Join device is it.
