Sorting by item type produces unexpected order

[tnajdek]

Fetching items sorted by the itemType from the API use the raw value computerProgram rather than the locale-friendly Software which leads to an unexpected sorting. To fix this would require API change.

I guess as a start I can sort itemType on en-US localized strings, and then we can support the locale query parameter for /items requests?

Well, or we could do it automatically with Accept-Language, which would probably work for web-library, but maybe we want to keep the API explicit? Sort of weird to have that one thing use content negotiation?
