Localized item names

[Istador]

Follow up to issue #15.

The current beta build only offers the English language, but the final game is going to be translated into several languages.

To offer localized item names in the map, the strings should be extracted from the game.

• [x] English
• [x] German
• [x] French
• [x] Italian
• [x] Spanish
• [x] Dutch
• [x] Portuguese
• [ ] Chinese (too hard to transcribe for me)
• [ ] Russian (too hard to transcribe for me)
• [ ] Korean (too hard to transcribe for me)
• [ ] Japanese (too hard to transcribe for me)

Chinese, Russian, Korean and Japanese need to be copied from the game assets (somewhere) or being transcribed by someone else than me. It's too hard for me to transcribe them character by character without proper keyboards for it.
