Env and profile

Using [figaro](https://github.com/laserlemon/figaro/blob/cc0c45186dd6b5cdb80b4ac83989a33e36eb3a4c/README.md) gem instead of our own local_env since figaro has nice heroku deploying (see the readme).

Create an application.yml and fill it in from https://gist.github.com/SamLau95/05453ac3cb89c7807f73

I did my best for the user profile page and idk how to beautiful...but I tried.
