Issue if custom server not running at port 22

[lhoracek]

In that case add-on executes:
Running '/bin/bash -c 'sleep 15 && ssh -tt -o ExitOnForwardFailure=yes -o StrictHostKeyChecking=no -o ServerAliveInterval=10 -o ServerAliveCountMax=3 -R hassio.server.com**:2222:80:**localhost:80 [email protected]:2222'' through supervisor!

There is PR #4 that should resolve this issue, I'll wait for creator of PR to update it, in case there will be no action for a week I'll do it by myself.
