[Main] Add my launcher (AutoItV3 -> Compiled Version included) - It can create Shell extensions and very useful for external programs like e.g. Total Commander -> Syntax is "CygwinPortable.exe FOLDER" to open a folder or  "CygwinPortable.exe FILENAME" to open a file in cygwin (see PortableCygwin.ini for allowed extensions). If you set SetContextMenu in ini file to false Shell Extensions will be removed.
