Description of problem:
The Thunderbird menu entry is not translated. I'm running my desktop in Finnish
and still the Thunderbird menu entry is "Thunderbird Email", when in should be
"Thunderbird-sähköposti" or something similar.

The problem is that there are no translations in the file
/usr/share/applications/mozilla-thunderbird.desktop . If you compare that to
e.g. /usr/share/applications/redhat-evolution-mail.desktop, you'll see that it
has lots of translations.

Version-Release number of selected component (if applicable):
thunderbird-2.0.0.6-6.fc8

How reproducible:
Always.

Steps to Reproduce:
1. Open the Internet menu in either KDE or Gnome when running the desktop in
Finnish or some other non-English language.
  
Actual results:
The Thunderbird menu entry is not translated.

Expected results:
The Thunderbird menu entry should be made translatable and after translators
have translated it, it should show up in the language that the user is using.
