Part). Implemented 'history (xpdf's LinkAction) links'. History depth is 100 steps by default (this is enough for sure, clicking 100 times on a button is not an easy task :-). Minor issues (removed half TODOs in code, all FIXMEs are already removed): Invoke mailer on 'mailto:' links inst instead of konqueror. Actions cleanup: disable actions like 'print', 'preview', 'save to..', etc when there isn't an active document. Added history actions to the toolbar in place of the 'prev_page' and 'next_page' ones. Fixed open+open_recent action tooltip and behavior. Move definition and implementation of PagePainter class to ui/pagepainter from core/page. Valgrinded and leakchecked (2 memory leaks spotted and fixed (missing contents deletion in KPDFGeneratorThread and missing deletion of PixmapRequests on cancel in Document::requestPixmaps())). svn path=/trunk/kdegraphics/kpdf/; revision=382960
