This works, thank you. Pushed to master with expanded docstring and a 
minor fix (the ARG argument).

Also added the below patch.

This seems to work well, so marking this as resolved.

Greetings devs and emacs community.

I occasionally need to list buffers of a project and do so with the
built-in command project-list-buffers from project.el. The problem is
that this command utilizes Buffer-menu mode and does so in a hard-coded
way. Personally I prefer IBuffer which is already heavily customized
while I have zero knowledge of Buffer-menu mode. 

I suggest to make an option whether project.el will list buffers with
Ibuffer, Buffer-menu or even something else?

Kind regards,
-Mikhail
