[meld] Move selected translations out of frequently executed code

commit ddea72bc2ea8bc92a742ed9b2d888d520ea8dd3b

    Move selected translations out of frequently executed code
    
    Scrolling through commits using the keyboard shows up the translation
    of the line/column and overwrite labels as unusually expensive calls.
    This patch eliminates this overhead by caching the translated strings.
