msvc: add No_SafeExceptionHandler option

Browse Source 
Microsoft flipped the Windows Safe Exception Handling default
in VS2013 so that zlib became unacceptable to certain OS versions
(Vista and subsequent 32-bit OS's) without the addition of
the option -SAFESEH:NO.

Provide a switch to disable the Safe Exception Handler when required.

The option ImageHasSafeExceptionHandlers for VS2013 is not available in
earlier versions, so use the SAFESEH:NO linker flag. See
https://msdn.microsoft.com/en-us/library/9a89h429.aspx for
further details.

This has only had limited testing due to the lack of a suitable system.
