Some contributors seem to have a shift key stuck here or there. Many 'stylised' capitalisations weren't reflected even on the manufacturer's websites, or were also stylising words like 'pro' and 'dual' or even actual chemical names like 'nylon'. Normalising the caps makes it more fair for everyone, since all of these are written in the same font.

They are not being used any more. For some reason people thought that an exception was made for extruders or something. And people keep adding them for the definition files too. I'll add a test to prevent that.
