Controller reads should be reasonable when it's not connected

[GoogleCodeExporter]

Currently the return values of controller functions are undefined if the
controller is not connected. There are, in fact, different responses on
each platform. 

While this can easily be gotten around by the client code checking if the
controller is connected before reading it (which is probably a smart move
anyway), we should ensure that reasonable defaults (no buttons down, both
thumbsticks at center) are returned when there is no physical controller
connected.

I can take this if you like.

That'd be keen. I think on Windows we just need to make sure the memory gets 
zeroed
when the controller isn't connected -- right now it only gets zeroed when it's
*disconnected* in the middle of play. The mac side is a little wonkier, but I 
could
handle that. 

The more straightforward and cross-platform way would just be to have every 
relevant
function do a check to see if the controller is connected beforehand, but that 
seems
goofy to me for some reason. What do you think?

I've got a change ready.   Maybe you can check the Apple side once I get it 
checked 
in?

Sure, go ahead and check it in, and I'll poke at the Mac side when I get a 
chance.

At long last, this appears to be done.

Looks like it fell off my radar.   :)
