all the reviews on the document (pretty unuseful now, but that will
change ;-). Another step to good kpdf annotations.

Part:
  Added Reviews toolbox pane. Added (commented out while doing it right)
  searchline for toc; just works.
Misc:
  Observer: added id for Reviews pane (as document observer it monitors
  document/annotations changes). Page: added 2 temporary accessors for
  annotations (will change soon). Makefile: added side_reviews.cpp to
  compilation. Searchwidget: slight better spacing to look consistant with
  the review panel.
