[STUMP] [PATCH] Add the standard Make target `info'

`make stumpwm.info' continues to work, but `make info' is the usual
way for building Info manuals.

This also uses an implicit rule to build the Info manual.
---

I am sorry.  It is the standard "target", not "rule".  Please,
disregard the previous patch.
