Small changes, Spanish models added

Hi,
I have been working with Wikiminer for two years and I have some code to share!, 

Apart from the small changes I have added some options to the web services that I'm going to merge too.

The first one is support for list query in the web search services....


I have been also thinking in adding EHCache support instead of your caching mechanism.... What do you think?



Thanks for your tool.
