Change the default functionality of Space key or at least allow to change it

Hey,

I'm not sure if this is a right place to post suggestions, but I 
couldn't find a better place.

I like Rhythmbox a lot, but there is one thing that really bothers me; 
the function of the space bar. 99% of media playback software use space 
as pause/resume key, Rhythmbox doesn't. I find it confusing to have a 
combination differing from the majority of such software.

What I'm suggesting is to either change the default functionality of the 
space bar to pause/resume, or at least allow user to change it from the 
settings.

Best Regards,
Lassi
