community/libvterm: upgrade to 0.1.4
This had me confused for a bit, like, what is the right place to pull this from?
Our previous upstream source has no releases but a 0.1.3 bump over a year ago https://github.com/neovim/libvterm/commits/nvim
no 0.1.4 download from here https://launchpad.net/libvterm/+download linked from here http://www.leonerd.org.uk/code/libvterm/libvterm-0.1.4.tar.gz
But Ubuntu and Debian seem to have packaged 0.1.4, as well as void-linux https://github.com/void-linux/void-packages/blob/master/srcpkgs/libvterm/template
