UI: Display filament material in the dropdown when creating spool

[TomW1605]

currently when you add a spool and select the filament from the dropdown it shows vender and name (usualy colour) but not material. that means that do see what material it is in the dropdown you need to put it in the name as well as in the material section. but then in the spool list you end up with the material listed twice.

i recomend adding the filament material to the dropdown along with name and vender so you dont need redundent information in different fields
