bug#7757: 24.0.50; list-load-path-shadows should be documented in lispref manual

[emacs18]

I recently stumbled onto list-load-path-shadows command defined in
shadow.el.  This is a very useful command, but it is not mentioned
in the lispref manual.  I took a stab at adding it to the manual as
shown by the diff below which adds a few lines at the end of the
"Library Search" node in the manual just after the documentation
of locate-library.

Thanks.  I edited this and committed it to the branch.
