Create get-ghcup.sh, fixes #36
This follows the style of the rustup installation script that has a friendly welcome message, tells you what the script is going to do, and then asks if you'd like to proceed. This is meant to be a one-command setup of everything you need to get started with Haskell.
I already had this written so adding it for comparison to #40. Would still need to update README and clean a few things up. Let me know what you think!

Yeah I wasn't sold on this either, the rustup script does something similar, but adds it to .profile which is arguably the correct place. I used .bashrc to mirror the readme instructions but you're correct this could very well break things. It would be nice if system configuration was a bit more structured :)
