[Translators] Updated Spanish (es) translation

[pico.dev .]

Hi again!

I have merged the changes I made with the base po file from
http://git.videolan.org/?p=vlc/vlc-1.0.git;a=blob_plain;f=po/es.po;hb=HEAD

Now the number of strings in the base file matches the number of
strings in the new file.

New Spanish Stats:
97% translated, 5120 strings (81 fuzzy, 0 bad tokens, 36 not translated)

New updated translation:
https://docs.google.com/uc?id=0B4yquUFv3csrYjkxOWYyYmYtM2Q5Yy00Y2IzLWJmZTUtMjliMzI4NTIyMjRi&export=download&hl=es

Please commit this and forget the file in the previous message.

Thanks,
