Add a mod!... syntax for suppressing any number of frames within a module

I've been adding more default suppressions, and I was thinking it would be useful to be able to match "mod.dll!...", meaning "any number of frames from this module."

Without symbols, we have reports like:

We don't have very many exports to identify the report, but we do have lots of modules boundaries. I'd like to be able to match lots of internal frames, and then an export in another module, followed by more internal, and so on, like so:

LEAK
name=issue #12 One-time RPC handle leak
RPCRT4.dll!...
RPCRT4.dll!RpcBindingFromStringBinding*
MMDevAPI.dll!*
ntdll.dll!*
kernel_.dll!InitOnceExecuteOnce
MMDevAPI.dll!...
ole32.dll!...
ole32.dll!CoCreateInstance_

Replacing all of those module ellipses with regular ellipses would make the suppression too loose.
