Subject: [PATCH] Boost-1.65: fix another integer ambiguity problem with
 boost::rational

<rant>
the "improved" boost::rational can no longer compute 1/x
quite brilliant
</rant>

well... the reason is again signed vs unsigned int.
FrameRate is based on unsigned int (since a negative frame rate makes no sense).
