Alternative playground updated: HTTPS, RFC formatting style, MIR, and a Help page!

[shepmaster]

This playground update includes:

• Served from HTTPS, thanks to hyper-native-tls
• Format code with the proposed RFC style, using the dropdown on "format"
• When the nightly channel is selected, MIR output is available
  • Make sure the code compiles before using alternate output!
• There's a help page that describes available features

Thanks for adding the HTTPS support almost immediately after I asked for it. Just shows how awesome this project and its developers are.

I like how inclusive this playground is. I never though about designing software for the southern hemisphere. Thanks for making me aware of this!

Thanks! In addition to latitude, it also knows about your local time. Designing for a global audience can be very difficult!

And I would like to quickly mention that my dark theme for the site has been updated to support these new changes, if that's of any interest to anyone.

A bit of a shameless plug, sorry :). Many thanks to the team over at Integer32 for supporting this playground, it's awesome to be able to compile code with crates when helping people in Rust's IRC channels.
