Implement pfCrashHandler

pfCrashHandler includes a client that watches plClient for crashes. When
it detects a crash, it lets the plCrashSrv (plCrashHandler.exe) know about
it. We then produce a mninidump, then signal the client that it's OK to
show a crash dialog. See http://www.nynaeve.net/?p=128 for a good
explanation of why I split the crash logic into another process.
