Spanish Translation

I added the translation into Spanish, in addition, using the idea behind [meteo-qt](https://github.com/dglent/meteo-qt) I did a [program](http://codeshard.github.io/prognos/) written in Python and Qt4 but adapted to my country(Cuba), using the [INSMET](www.insmet.cu) as data origins, this site does not provide a web service, I had to parse RSS(quick and dirty solution). Many people in my country do not have access to weather forecast services due to internet restrictions.
