add new stateless mode and test compatibilites

[ewsopp]

• Add the new "Stateless" mode that does not use local storage at all.
• Determine which compatibilities work and which compatibilities do NOT work with this new mode.

@ewsopp With new "Stateless" mode I can't add files to Bucket root. It needs to have folder in Bucket.

So new field Folder shouldn't be empty for "Stateless" mode

Imagify add mediafiles to local server

Should we just default to the standard Wordpress organization scheme?
