Add config option for faux scrollback
Some people have complained about the behavior of faux scrollback inside
of vim/tmux, however from what I can tell, alacritty behaves the same
way as other terminal emulators that support faux scrollback.
However there are a lot of terminal emulators that do not support faux
scrollback at all, which leads to people complaining about unusual
scroll behavior.
This is my proposal on how to solve this issue, by giving people that do
not like the VTE-Style faux scrolling the option to opt-out.
