some consideration on NSWorkspace

[Enrico Sersale]

The recent changes in NSWorkspace don't let anymore GWorkspace to launch
applications with double-click on an icon, a fiend tile or a browser cell
that represents an application.

Ths happens because the changes in NSWorkspace affect also
_launchApplication: that, before, accepted also a path as argument.

Well, this wouldn't be a big problem because I could modify the
GWorkspace's methods where -launchApplication: is called to use the
application name instead of the path.

But one case remains in which, this new beaviour, represents a problem;
if, for example, I've "myapp.app" in $GNUSTEP_SYSTEM_ROOT/Applications and
also an "/home/enrico/myapp.app" and I want to launch *this* myapp.app
double-clicking on its icon, NSWorkspace will launch
$GNUSTEP_SYSTEM_ROOT/Applications/myapp.app anyway.

I think that -launchApplication: should accept a full path to the
application, too.
Or, pherhaps a better solution, we could let - (BOOL) openFile:
(NSString*)fullPath (in this case we have specifically "fullPath" in the
method name) to launch an application if "fullPath" represents such an
object.

An other thing: on openstep, if I give an "open /home/enrico", a new
viewer window, rooted at /home/enrico will appear. I think that -openFile:
should call the -application:openFile: method of the _workspaceApplication
(that I could easily implement in GWorkspace), if "fullPath" represents a
directory. Doing this, gopen would have the same behaviour...
