ProjectCenter triess to remember the path that was used to open the project.

However from a bit of debugging, I found that if "ProjectCenter file.x" 
is invoked on the command line,

- (BOOL)application:(NSApplication *)application openFile:(NSString 
*)fileName

fileName results in just the file name, not the absolute path.

When using "NSDocument" methods, that is open file, open recent and so 
on, I correctly always get a full path.

 [[NSURL fileURLWithPath:fileName] path];

Fixes my troubles, but I wonder then if I need to do that or not. If it 
is correct that application openFile doesn't get a "normalized" file 
path there.
