ref-manual: Review comments added, new variables added

* Updated some links in the insane.bbclass sectioni so they
  now point to some new variables.

* Added glossary descriptions for PKGD, PKGDEST, and
  INCOMPATIBLE_LICENSE.

* Added a paragraph to the LICENSE variable to describe
  situations where the output might have components whose
  licensing is from two different licenses (licensing on
  a per-package basis).
