This is the start of plumbing things through into the theme files, but I
do think that there is a better way here. I'm open to suggestions and
will probably ask for some help in the Discord for Catppuccin.
This option, for now, defaults to false. This is just so it keeps the
initial design intention for the original design of the plugin. I may
flip it or change the name of the variable in future commits. This patch
is addressing catppuccin/tmux#16.
