Help system

[JP Rosevear <jpr cr168790-a nmkt1 on wave home com>]

OK, I wrote some help docs for the GNOME Search Tool (there weren't
before) but I'm missing a step to properly have them compile.

I copied over the ghex help directory and replaced the appropriate
files.  I added a SUBDIRS line to the gsearchtool Makefile.am to include
the help directory.  However when I autogen the Makefiles, the
gsearchtool/help directory is not setup properly.

What am I missing?
