add Libraries in sub folder of Arduino libraries folder

[mkeyno]

hi
I intend to add my libraries in special folder in Arduino libraries folder like following temple
libraries/MyLibraries/lib1,lib2,lib3,.........
but according to this PR its not allowed yet , also I found that Arduino stop loading any folder content when it doesn't find any header file (*.h), so I was wondering, if it possible to create header file like "MyLibraries.h" in the MyLibraries folder and addressed new libs in it
