disable exception handling warnings in windows client code about google-breakpad HOT 8 CLOSED

Can we get away with putting these #pragmas into the .cc files?  If not, will 
this do
what we want in the headers?:

#pragma warning( push )
#pragma warning( disable : 4530 )
[...file contents...]
#pragma warning( pop )

I want to affect the warning state for other code as little as possible.

I think you can put them into the .cc files, yeah, or you can do the push/pop.  
You
just have to have that warning disabled while you include std::*.

Amended to push/pop in the headers, and I had to stick a disable in one cc file 
as
well.  This gets rid of all of those warnings in my build.

We've added a number of new files since this patch was initially created.  Ted, 
could
you provide a new patch?

Updated to tip.

Oops, plus that comment in crash_report_sender.cc.

Checked in, revision [56].
