Suppress duplicated definition warnings for conditional compilation

[sehHeiden]

From my university I got an latex template.

It's multilingual in that sense, that it uses ifgerman and only uses one of the newcommands.

Still I get the warning: Command '\thesiskind' is defined multiple times

Code example:

\ifgerman{\newcommand{\thesiskind}{Masterarbeit}}{\newcommand{\thesiskind}{Master's Thesis}}

I assume this is not top priority.
