- Add Extender functions in some places. Hopefully will add in all functions after more rewriting.
- Add Backblaze B2 uploading support
- Add support for managing cloud storage space used
- put all cloud video management functions in one library file using Extender
- separate uses of "s.s". s.s = JSON.stringify again and API calls with s.s will use "s.prettyPrint"
- move ffmpeg init functions
- rename s.beat to better reflect purpose
