Improve documentation of buffer-list commands and features

* doc/emacs/buffers.texi (List Buffers): Add a cross-reference to
"Several Buffers", to establish a relation between the two
sections.
(Buffer Menus): Expand on customizability of alternative buffer
menu offered by bs.el.  Mention IBuffer.
