Updating Richard Feldman's Frontend Masters course links

[iteles]

Whilst reviewing the resources in the readme, I noticed that in October 2018, there was a new version of @rtfeldman's Frontend Masters course, with the addition of 'Advanced Elm' with v 0.19.

https://frontendmasters.com/courses/intro-elm/ + https://frontendmasters.com/courses/advanced-elm/

I haven't included the contents screenshots here because they are quite extensive and detailed in the links.

Might be worth subscribing for a month to soak up the wisdom and then updating the readme to reflect our recommendations?

@iteles totes down for re-subscribing. Want to pair on watching these videos for 30 mins / day? 📆
(I really wish Frontend Masters had a buy just this course option instead of subscription model ...)

@nelsonic It's a date. Tomorrow at 08h00 for 30 mins (if we can get out beauty sleep in time before that!) 😘

Totes up for watching and making notes with you. ❤️
