ref-manual: Edits to classes "I" through "K"

Added opening reason for the icecc class. Also cleared up the
sentence describing ICECC_PATH.

Minor fix to image class. Also added some reference
links.

Minor fix to image-mklibs class.  Also combined rouge
sentence stating that the class in enabled.

Same fix to rogue sentence in image-prelink class.

Fixed "insserve" into "insserv" throughout.

Added many links to some missing classes in the kernel
class.  Subsequent commit to actually add the class
documentation.
