[Qt-creator] Translating QtCreator

[Jochen Becher]

Hi, 

I want to update the QtCreator translation to German regarding
ModelEditor plugin. 

How do i create the correct .ts file? Is it correct to run "make ts-de"
in target ./share/qtcreator/translations? There are a lot more
differences in the resulting translation file than I expected (e.g.
added source code locations and a large number of new unfinished
translations besides those from ModelEditor plugin).

Regards, Jochen
