Translation files updated accordingly.

 - Many punctuation fixes
 - remove "please" (like in the GNOME project).
	The translation guidelines at
	http://gnome.org.ru/wacko/TranslationPrinciples

 - 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!).
