Added Traditional Chinese translation

Hi @tsunglung

1. Any reason for providing the translation as unicode tags instead of just Chinese text? It would be better if the translation was readable to humans.
2. You need to to provide the select translation file as well (you can just copy the sensor file).

1. From Python document Python’s string type uses the Unicode Standard for representing characters, which lets Python programs work with all these different possible characters. Also using unicode saving is better for multiplatform (Windows, MacOS, Ubuntu). And HA core also uses unicode in translation files.
2. As attachment. sensor.txt

The comment wasn't about unicode per-se but about using the encoded unicode tags instead of just the text, which by the way works just fine and is much easier to understand. However, I see that you are right and most translation files in the core HA take this approach, so I'm going to commit it like that although I think it's a bad idea.

Thanks for contributing
