Title: Make new weather provider strings translatable, correct untranslated strings due to different string case

I realized that with the new weather provider a lot of strings showing up untranslated. There were two reasosns for this:

- A lot of weather tokens had different case and the routine that searches tokens was case sensitive.
- There were a lot of new weather state descriptions which were not there with the old data provider.

To correct these problem I introuduce two commits:

1. Make token search case insensitive, so that changing weather provider wouldn't mean to change all tokens because of capitals.
2. Intruduced the missing tokens for Weather Underground. The possible strings can be found here: http://www.wunderground.com/weather/api/d/documentation.html

Please backport these also into the Eden branch if possible.
