SafeSEH reported False for resource-only DLLs #16

SafeSEH is reported False for resource-only DLLs. While it is technically valid, it just generates a noise in the reports as this can't be 'fixed' in the DLL itself. Resource-only DLLs contain no code, so they can't have safe Structured Exception Handlers. PESecurity could skip such DLLs by checking whether they have non-0 entry point.

Thanks for the info. I'll take a look and write up a patch to skip those.
