dev-manual, ref-manual: Updated some section titles.

I noticed that chapter 10 of the ref-manual still had
"Reference: Features" as the title.  This is left over from way
back.  I changed that chapter title to "Features."  Next, I
noticed an inconsistency with some sub-section titles.
I changed the "Images" title into "Image Features."  This affected
several links across the doc set so I had to update those
cross-references as well so they have the latest section title
as part of the reference.
