Update CrashRpt version from 1.4.0 to 1.4.2

Install a SEH handler to trigger a crash report when an async
task raises a SEH.  The new version of CrashRpt gives us access
to a SEH filter function, and allows us to install handlers on
other threads without modifying fc.  Disabled CrashRpt in debug
builds, where it usually gets in the way.

CrashRpt binaries are just taken directly from the official
release.
