pluralization in dialogs
Bug description
the "Added %s contacts" and "Removed %s contacts" lines (RosterItemExchangeWindow) are not pluralized, resulting in "Added 1 contacts" or similar messages.
Steps to reproduce
have exactly one contact sent to you, accept it, and see the message.
Software versions
PyGTK version: 0.15.1 to hg head (14117:6993af372e75)
the attached patch fixes the problem in the code and the german translation. as gettext requires a number to decide pluralization, the overly stringifying "%s"%str(a) was replaced with "%d"%a, and abundant whitespace was removed.
