live_mode when set to false should not need to call NHL API

[harmgsn]

When I set live_mode to false in the configuration it should no longer need to reach out to the NHL API information. Or provide an option for "offline mode" where it doesn't do this. During the off-season the NHL API has gone down a couple of times (like today, where it's DNS doesn't resolve anymore) which has put the scoreboard into a crash loop even though I have live_mode turned off.

That would require a full rewrite of the code to handle how the data is pulled. @riffnshred and I have discussed this but it is a large job to redo it. Now with the API looking like it's been changed, it might be time for a rewrite.
