documentation/poky-ref-manual: Added new title graphic

I have removed the multi-colored POKY image that was used for
the title of the Poky Handbook.  The image I put in here is in
line with the other graphics used as titles for our Yocto Project
documentation.  To accomplish this I had to create and add a new
PNG file named poky-title.png.  I placed this image in the figures
folder.  I removed the poky-ref-manual.png file (old figure).
I also had to alter the Makefile to use the new figure as part of the
tarball.  Finally, I had to alter the HTML style sheet (style.css)
to include the new file.
