[IDEA] XBMC tagging foreign languages

[syco]

The problem is, the German (or other languages') names of the
movies are often the same. Here some examples:

Vicky Cristina Barecelona (same in Spanish and German)
Silver Linings Playbook (Silver Linings in German)
...

So, I do not care about foreign languages information or
titles. I just need those films tagged somehow, e.g. with
an asterisk by the file name or so.

Even if I would have to tag them manually, I would not mind.
It should just be shown in XBMC in the movies list or when
watching per Yatse throuth the list.
