Include <cmath> so abs(double) can be found

During the exp-run in bug 208158, it was found that games/chromium-bsu gives
errors with libc++ 3.8.0 [1]:

MainSDL_Event.cpp:420:73: error: call to 'abs' is ambiguous
                if( keystate[SDLK_LEFT]  || keystate[SDLK_KP4] ) key_speed_=
x -=3D
2.0 + abs(key_speed_x)*0.4;
=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=
=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=
=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=
=20=20=20=20
      ^~~

This is because key_speed_x is a floating point value, but <cmath> is not
included, and abs() for floating point values comes from that header.  Fix =
it
by including <cmath>.
