tether.js doesnt run with newer versions of node

[devlin016]

I can compile your version of node to work on a raspberry pi and the tether works but the performance is low I read online that newer versions of node are way faster so i installed node via nvm and edited run.sh to use the binary nvm installed and it gave me back this output. please edit tether.js so it runs with newer versions of node I have already purchased this app.
