Translation updates

Added a RetranslateMixin. Since PyQT does not support automated language
changes of UI files (like the C++ QT does), this implements something
similar. It assumes that the UI file has the same name as the class, but
lowercase.

Added RetraslateMixin to the new blacklist and networkstatus interfaces.
