Enrico Ros b1ad685b54 Small API fixes. Preparing for mem-manager / async-gen. Removed KPDFDocument
dependancy from QObject. Kpdf_Part is now a Document Observer (only monitors
page changes to update actions).
Modified Accessibility(Recolor) settings and config dialog, fixed a bug,
page color change on-the-fly (pixmap refresh mechanism to add..).
