PATCH: escape \ in shell link

[Marcus Meissner <meissner@suse.de>]

Hi,

KDE hat path entries like:
Path=wine "c:\Lotus\Notes\notes.exe" --

KDE tried to execute
wine "c:\Lotus\Notes
otes.exe" --

evaluating the backslashes as shell escapes.

This patch just doubles the number of escapes. The same 
goes for the arguments.

Ciao, Marcus

Changelog:
	Escape \ in path and arguments.
	Use UNIX style work_dir, not windows dir.
