Set the uploaded file path to site/temp by default. Can be set via configuration with "temp-dir" variable.

(This is important, otherwise it uses the current working directory, but for fcgi, this is not always obvious where it is.)
Allow advanced upload, and also basic html upload, in case the dropzone.js has trouble.
Split get and post handling for files module upload request.
