Ruby OAuth file uploads

gistfile1.rb

# patch OAuth class to be able to create multipart requests (required for image uploading)
# NOTE that for my purpose I simply made it "auto-sensing" that an image is passed and
# only then creates a multipart body. You may simply want to use some flag instead or whatever.
