added where requested by the translators and recommended by Krazy in situations where
the right translation would be unclear.

Only major code change is in tagrenameroptions.cpp which I don't like in the version
either now or before.  Now it is more verbose but less of a hack.

Also trackpickerdialogbase.ui required hand editing since Designer doesn't support
changing K3ListView columns.
