This commit does not improve overall structure in gajim in a logical way.
It seems untested (is broken) and is therefore rejected.

Also use % formatting instead of string replace.
Translation files updated accordingly.

 - Many punctuation fixes
 - remove "please" (like in the GNOME project).
	The translation guidelines at
	http://gnome.org.ru/wacko/TranslationPrinciples
	warn against using "пожалуйста" (please)
	in Russian technical texts.
 - change voice/aspect of some verbs
 - Fix a space before bang in a string.
	AFAIK, French is the only language to use " !",
	all other languages use exclamation marks without
	spaces (certainly true for English!).

verified and NOT verified is _NOT_ both "Verwende Authentifizierung".
That's just super wrong and leads the user to the false impression of
security.

Restore better translation of moods (why was that reverted?)

  (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.
