Ubuntu 18.04 Release

Ubuntu 18.04 will be out today, and it's looking like a nice release! https://www.omgubuntu.co.uk/2018/04/ubuntu-18-04-whats-new-video

On the one hand, I should probably wait a month or two for 18.04.1 as stability is my top priority these days. On the other though, *colour emoji support* 🎉
