[pkg-wine-party] Bug#511310: add winefile into the menu

[Wei Mingzhi <whistler_wmz@users.sf.net>]

well choose to open a .exe file with Wine in Nautilus or Konqueror
will result in the working directory being set to the home directory
instead of the directory where the .exe file is located, which doesn't
always work.

however for newer versions of wine, the open-with command has been changed into:

wine start /unix %f

instead of "wine %f" in the .desktop file included with the official
package (wine-1.1.x/tools directory), which resolved the problem.
maybe it should be changed in Debian as well :)
