Comment 7 for bug 587123

@Michal Hruby: are you sure that people will think more about those strings if they are lost in one of existing .py?
These are quite long already, an extra file with an explicit name seems better to me.

It can be named "weather-days-and-conditions" if you prefer.
It can be a .py too, so even if it is never executed we can hope that people will be curious enough to open it (if you thing that no-one may notice a simple "weather-i18n" file).

I'm waiting for a decision before updating my branch.
