Switching to Termite because URxvt has weird rendering issues when
resizing the font.
i3-sensible-terminal needs the TERMINAL environment variable to launch
our prefered terminal emulator with the Ctrl+d binding.
Bash and Zsh both need a hook to enable Termite to open another terminal
in the same directory with the Ctrl+Maj+t binding.
I prefer having them available to change the indentation of a block of
code instead of having an easier time using vim-unimpaired, which I
haven't even bothered trying to learn yet...
