+ busybox --install [-s]

Browse Source 
is almost good to go.  Here is my work in progress.

+ Look at the FIXME in busybox.c
  to see what I need.  The actual (sym)linking is disabled
  for now, although I'm sure it works ;)
  (Am I going to have to dig through /proc to find
  out where the currently running busybox is sitting?)

+ I put an #ifdef BB_FEATURE_INSTALLER around
  the new bits of code in busybox.c, and I have a
  #define BB_FEATURE_INSTALLER in busybox.def.h
  towards the bottom.
