[i18n] Updated Spanish translations

[Manuel María Pérez Ayala]

Here you have the spanish translations on main horde4 app  
(horde,gollem,ingo,imp,kronolith,mnemo,nag, turba) and all framework  
modules. All of them updated from git at 2012-01-23 11:00 GMT+2.

I left the old strings from current release version in the main  
horde.po and some others to allow their use with existing horde4  
stable installs without the need of update.

Hope this helps
