Added: Strawberry v5.28.1

Added: Win32::Daemon v20131206

I have an implementation of Win32::Daemon that is working on some systems and not on others. The only common thread I've found so far is that the bulk of systems it is not working on are Windows Server 2012 systems.

The system I am currently looking at though is Windows Server 2016 Standard 1607 14393.2969 64-bit with Strawberry Perl

The state starts at SERVICE_STOPPED, switches to SERVICE_NOT_READY, and then stays there. The state never switches to SERVICE_RUNNING

Nothing in the Callback_start is printed.

To run:

cd \Users\john\test
perl test-svc.pl --install
net start TestService

I've stripped down the program to one file as shown below to help troubleshoot.
