enlightenment_filemanager - call EFM from another process.

This is used to open a file manager window from another process. It
will use DBus interface:

     org.enlightenment.FileManager.OpenDirectory(path)

It returns immediately, but we could enhance the DBus interface and
make it act like a real file manager process if that is needed.
