Allow configuring additional url schemes

[lewis-smith]

For mobile apps it's sometimes desirable to shorten deep links.

Hey @lewis-smith, I love this idea!

I'm wondering if it'd be better using a short-url.allowable-url-schemes config value instead? That way, in the package's config file, we could have http:// and https:// already set in there and any more could be added to that list in the dev's overridden config file. I guess this could be handy because the dev could also remove the http:// prefix if they only want to allow https:// URLs too. Do you have any thoughts on this? 🙂

@ash-jc-allen I'm glad you like the idea :)

From my perspective, in the short term I just want to create links to my app and so as long as I can do that I'm happy to go with whatever approach your recommend :)

I suppose the risk with your approach is that if you move http and https into config it would break existing installs? Maybe just http goes to config?

@lewis-smith Sweet! I should have a bit of free time later today, so I'll make a couple of small updates to this PR and then get it merged 😄
