patch: scrollback-mouse-increment (custom rewrite)

Apply the following patch on top of the first two to allow changing how
fast the mouse scrolls.

I had to manually reimplement this patch myself, since the version from
suckless.org doesn't apply cleanly on top of the first three when
starting from commit bda9c9ffa645.

In addition to fixing-up this patch so it applies to the previous HEAD,
a comment is added stating that the codes sent while scrolling in
alt-screen mode (the btn 4/5 fallbacks) need to be maintained along with
the preferred mousescrollincrement setting so the two modes scroll the
same, which they currently do.
