Make full translation easier

More info on how to translate the interface, maybe with some string moved to the settings.h file

Justification

I'd like to translate the whole interface to Italian (or any language): setting the proper language code in the settings for WU does the trick for 90% of the interface, but some stings remain in english and others are buried deep in one of the libraries used and not easy to find.

Workarounds

I can see that some of the strings are in the main code in esp8266-weather-station-color.ino, and they can be edited in place, but it'd be much better to have them collected in the settings.h file.

I'haven't found yet month/ weekday names that must be in some library. I have a custom version of the Time library from the Arduino Core where I changed month and weekdays long and short, but it clearly picks the names from somewhere else.

The month and day text comes from WU, if you select IT for your language, does it not give you month / day in Italian, I thought WU then output in your language, maybe not.

It's only partially true: on top of the clock there're still english short text (see image). Also in the bottom part "Sun" and "Moon" are in english (but they're in the main

code and easy to replace).
