[Mac] Additional crash logging for -sendEvent: crash.

[Mac] Additional crash logging for -sendEvent: crash.

-[NSEvent description] is what gdb's po command would print against
the event.  It is basically an ASCII serialization of the event.

I was implementing away, then realized that basically I was re-implementing this
but most likely with additional crashes.  I think this might be a bit
heavyweight to leave in forever, but in this case once there are a few crashes
on the server, it likely will either no longer be necessary, or can be replaced
with something more targeted.

What's the average length on these descriptions? IIRC NSEvent's is pretty long.
Will it fit within the key?

LMouseDown is around 135 chars, KeyDown 130.  Breakpad can take 255 bytes, I
believe things are trimmed if it doesn't fit.  It would be easy to cap at
something smaller.

A mouse down looks like:
LMouseDown loc=(287,787) time=1729836.3 flags=0x100 win=0x0 winNum=3555
ctxt=0x198ef evNum=25983 click=1 buttonNumber=0 pressure=1

time, ctx, and evNum are useless for this, win/winNum are debatable (title might
be preferable), loc is debatable.  So if we thought this had longer-term
utility, we could definitely improve on it.  But I think -description is
unlikely to wreak havoc on any users who have input devices I don't have.
