remove need for file name on upload, simplify API about transfer.sh

[nl5887]

Previous week I updated transfer.sh. You should be able to upload files without a filename now. Btw curl will append the filename of the uploaded file by default.

curl --upload-file /tmp/wifi-5m260z.log https://transfer.sh/
https://transfer.sh/168UV7/wifi-5m260z.log

When using --upload-file the file will be send as body, without any Content-Type or filename hints. That's the reason to send the filename with the request.

I see, would it be useful if we generated a fake file name and extension if no file name was provided? That way we at least give the user the option of not having to double type the name every time.

I'm planning an upgrade with a lot of issues fixed and enhancements, will take this into account as well.

@nl5887 check out file.io's api, no need to upload the file name also:
https://www.file.io/#one
$ curl -F "[email protected]" https://file.io
{"success":true,"key":"2ojE41"}
$ curl https://file.io/2ojE41
This is a test
$ curl https://file.io/2ojE41
{"success":false,"error":404,"message":"Not Found"}
