gpm support

[Lassebq]

While mouse events work just fine in a terminal, in a TTY, where the only way to use mouse is gpm, it doesn't.
The only file manager which I know supports gpm is midnight commander, if that may help.

lf doesn't read input events directly, it uses the tcell library to do so. There is already an outstanding issue there for gpm support: gdamore/tcell#297

I agree with the discussion in there that the support should be implemented inside tcell, and not in every application that uses it.

I see. Then I assume this issue can be closed?

I don't mind either way. Maybe it's better to leave the issue open in case someone else asks the same question later on.
