* Update some copyright years and mail addresses
 * Search does not block the GUI anymore YUHUUUUU
   Well, it it does but it's almost unperceptible, that means the searching methods of Document no longer return a bool but a void and the Document::searchFinished signal is used to know if something was found, nothing was found or the user pressed the cancel button !YES! one can cancel search now :-)
 * TextPage no longer holds the area and the current transformed area, it took TOO MUCH memory, now we transform the area each time, it's much more CPU intensive but i could not measure a time loss while searching big documents and i could measure HUNDREDS of MB of usage less.
 * MICRO optimization: Change some code to not detach some containers
 * I still don't have ADSL so this is something like a "blind" commit, Pino will check it compiles against current KDE, not against what's on my computers
