Update kdiff3 to 0.9.98

Version 0.9.98 - 2014-07-04
===========================
- Text rendering now with QTextLayout fixes the following issues
  - Correct handling for variable width fonts.
  - Corrected display of highlighted text with Qt4.8.x on Ubuntu and Mac.
  - Improved handling of texts with both right to left and left to right
    languages (mixed Arabic and western texts).
  - Improved handling of Chinese and Japanese.
  - Whitespace characters are now shown as dots for spaces and arrows for
    tabs, and not only in differences.
  - Fixed symlink comparison (Qt4 symLinkTarget returns absolute paths)

  multithreaded.  (See progressbar and abort-button in statusbar)
- Fix for saving to relative path in KDE-environments. (Patch from Harald Sitter)
- Fixed bug in 0.9.97: Directory compare was always case sensitive.
- Fix for saving files on KDE with relative path specified via command
  line option -o.
- Fixed problem with KIO (nonlocal urls).

- Write --confighelp information to stdout instead of stderr.
- Directory Merge Window: Enabled state of "Delete A And B" now also
  depends on existence of source file A.
- Works now with Qt4 and Qt5
- Progress dialog during printing.
- Workaround for bug in QSplitter::childEvent that broke
  QFileDialog::getSaveFileName
