dev-manual, ref-manual: Applied review comments for read-only-rootfs, etc.

1. Applied changes from Paul to the read-only-rootfs section.

2. Applied changes form Paul to the customizing images by using
   IMAGE_FEATURES and EXTRA_IMAGE_FEATURES variables.  This
   was a simple rewrite of a sentence.

3. Updated the note in both the IMAGE_FEATURES and
   EXTRA_IMAGE_FEATURES glossary entries to specify inside
   of an image recipe (more specific).
