support CJK text copy from wine to KDE and vice versa

[liu spider <liuspider@yahoo.com>]

When copy text from wine to KDE programs, I only got
unreadable characters and vice versa. This patch
solves this.

CHANGELOG:
- dlls/x11drv/clipboard.c
  Add support for QT's "text/plain" property to
support for copying CJK text from KDE programs to
wine;
  In X11DRV_CLIPBOARD_CacheDataFormats, exit for loop
after getting the first recognized format;
  Remove unused variable lRequestLength.
- dlls/x11drv/event.c
  Add COMPOUND_TEXT property for STRING additionally
to support for copying CJK text from wine to KDE programs.
