Upgrade WinSW to 2.0.1

[nxtn]

WinSW 2 carries a logging framework so the binary is a bit larger.

Also removes .NET 2 support. Who is using .NET 2 these days?

Fixes #47

Bug fixes

• Prevent CPU overutilization when waiting for the process to exit.
• Properly retrieve waithint, sleeptime, resetfailure, and stoptimeout options from XML configs with metadata before settings.
• Print warnings in the uninstall command when the service cannot be uninstalled immediately.
• Prevent failure when stoparguments are defined without stopexecutable in the XML file.
• Prevent failure during process termination if child processes cannot be retrieved due to the pending system shutdown.
• Security: Do not dump WinSW environment variables to the Event log.
• Do not propagate exceptions from Process.Kill() if the process actually exits.

Compatibility notes

• WinSW v2 is fully compatible with WinSW v1 in terms of the command-line interface and configuration files.

I'll consider this, depending on how much time I get. I've been working on an alternative to winsw, so this may not be necessary.

We're now building WinSW 3, and it's surprising to see this project is still using WinSW 1. A large number of issues in this repo have been resolved in the upstream.

Why reinvent the wheel? Is it written in Golang?

[coreybutler]

Yes, alternative is in Go. It's not recreating the wheel for me, because I'm building it for another effort.

Again, not opposed to merging this, I just need to test it/confirm and make sure I can continue to support it.

[nxtn]

Sounds good. I'm also considering rewriting WinSW in a different language, but I don't regard Go as a competitive choice. I would prefer a native language like Rust this time.

Would this also address issue #53 and allow node-windows to set a StartupType?

Yeah. There may be more ancient issues fixed
