Italics work in the terminal!

UPDATE: All you need is https://github.com/gabebw/dotfiles/pull/118, which is simpler, without anything from this PR.

Tell your Terminal.app theme to use a font with italics
- An easy, free way to do this is to install Iosevka: brew tap caskroom/fonts && brew cask install font-iosevka
- Then tell your Terminal.app theme to use "Iosevka" as the "Font" and restart Terminal. It'll automatically switch to Iosevka Italic when needed.
Run tic terminfo/xterm-256color-italic.terminfo
Run tic -x terminfo/tmux-256color-italic.terminfo
Set Terminal.app -> Settings -> Advanced -> "Declare terminal as" to xterm-256color
Kill all tmux sessions by quitting or with killall tmux
Quit your terminal
Start a new terminal and tmux session
To check if italics work, run this after it's all done: echo $(tput sitm)italics$(tput ritm)
