Continous/2-up modes done! :-) Need cleanups/smarter reLayouts but it's

fully functional now. Better and faster graphics in PageView and
ThumbnailList. I need the memory manager now.. mmm..

-> wrong zoom buttons order (BR74248) (check consistancy with kdvi/kghostview/.. (not konq))
Porting / In progress on the branch (first item comes first):
-> continous mode (BR74435)
-> multiple pages per view (BR80164)
-> restore single page mdoe (broke up)
-> zoom buttons in sync with text (BR69092)
-> porting Albert's link following
-> implementing async document generator using Albert's thread as the generation thread
-> reading aids (accessibility): mode: normal, invert, contrast, recolor bg/text
Done (sorted by inv.time)
-> continous mode
-> multiple pages per view
-> added the option to open password protected files (from head)
-> added the TOC from head (missing click and go functionality because it needs link following)
-> added a 'search bar' with prune-as-you-type feature
