Localization Issue: "Light" being shared for the theme and the encumbrance level

[Frerol]

Basically, in English, "Light" can refer to both a color theme and the weight someone is bearing, aside from other possible uses, and it may not be so with other languages, such as it is with Brazilian Portuguese. If the localization file could differentiate between the two things specifically for the "Light" word, it would help localize the program better. Such an issue could happen to other terms, such as "Dark", but I didn't check them.
