Subject: Hooked up Google Breakpad for the Linux client too.

Using Alain's Darwin reporter callback was all that was needed.

Also replaced the call that exposed the breakpad exception class
with a call to just write out the minidump, as that was the only
reason for exposing it. Now clients don't need to know about
Google Breakpad.
