    meld/melddoc.py: Fix windows external open (#354)
    
    When in a Meld folder comparison in Windows, a file or subfolder can be
    opened externally with default windows application (e.g. explorer for
    folders, previously selected application for files, or the windows
    file open option popup for unspecified types).
    
    Right-mouse button click and "Open externally" should produce this
    behaviour, however currently folders with spaces in the path produce
    unexpected behaviour such as command line windows opening.
    
    Changing the relevant system call from subprocess.Popen() to the
    windows-specific os.startfile() fixes this behaviour and handles paths
    with spaces in them in the expected way.
