ExplorerHotkeys: Implement Alt+Enter to open Props of current folder

[ewerybody]

.. If nothing is selected that is!
Originally Alt+Enter does nothing. One needs to right-click into empty space and go Properties.

ExplorerHotkeys_Props() {
    items := explorer_get_selected()
    path := explorer_get_path()

    if items.Length(){
        Send !{Enter}
        Return
    }
    cmd := "properties " . path
    Run, %cmd%
}
