Materials database & button to create spool into filaments creation

[llambion72]

I would really like to see a materials database and add it to filament create form on a dropbox field. If you select any created material on the dropbox field, autofills density, temperature,...

If you create a new filament, a good improvement could be a checkbox that create a new spool entry with this new filament data
