[Translators] Updated Spanish (es) translation

[pico.dev]

Hi!

Previous Spanish Stats (from
http://git.videolan.org/?p=vlc/vlc-1.0.git;a=blob_plain;f=po/es.po;hb=HEAD):
84% translated, 5120 strings (512 fuzzy, 0 bad tokens, 254 not
translated)

New Spanish Stats:
97% translated, 5094 strings (87 fuzzy, 0 bad tokens, 32 not translated)

Why the number of strings are different? I made something worng? I use
poedit for translate and I obtained the stats from it.

New updated translation:

Please commit if it is ok.

Thanks,
