(Lianja) Upload String to Dropbox

Uploads a string to a file on Dropbox. This example can upload content up to 150MB, assuming a 150MB string fits in memory for your app. Larger files must be uploaded with an upload session (upload_session/start).

// A Dropbox access token should have been previously obtained.
