* remove js from some headers
 * set coding:utf-8 to allow real names in headers

sorry)

we have that in all files. To at least lesser the confusion a bit, add
vim tags for that.
Additionally, fix wrong #! in a few files.

* Add the 'thoughtful' mood in the Gajim namespace (trying to get it in
  the XEP!)

  (Only takes space if needed now)
* Possibility to disable display of mood in roster from preferences.
  (Also works on the fly with the new rendering method)
* Minor improvements in the translation of the moods to German.

Woohooo! This is the 10000st commit to Gajim! Let's have a party!! \o/
