Update spanish translation and fixed some issues with some messages

[agarfu@…]

This is a patch against trunk.

This patch update spanish translation and fix some problems with messages on django/core/validators.py : 364 and django/contrib/admin/views/doc.py: 171, 183, 214

There is a problem that I can't fix in django/utils/html.py : 10

To sucessfuly update .po file I had to comment that line, then execute bin/make-messages.py -a -l <put your languaje here/> and remove the comment.

This is the error message whithout the comment:

./bin/make-messages.py -a -l es
processing language es
errors happened while running xgettext on html.py
xgettext: Non-ASCII string at ./utils/html.py:10.
          Please specify the source encoding through --from-code.

Thx for your amazing work and sorry for my awful english.

This patch has two parts: the part strictly related to the updating of the es translation and a patch to the Django code that is being discussed in #3410.

I dared to cripple agarfu's patch and eliminated the second part.

agarfu: You don' t need to specify the -a switch to make-message.py if you only intend to process one language.
