There is a Spanish language file in the source, but it has no translations in it ..
the included es.po file is a collaboration between Google translate,
my Spanish-English-Spanish dictionary, and various other sources.

Any involvement from a Spanish speaker to check and correct will be welcome.
Kbabel is not necessary, it will display in a text editor just fine.


Tested with gnuchess-6.2.2, stockfish-7-linux, and komodo-7, in UCI mode.
