Changes to the Graphical desktop clients section in Projects page; Windows client

[gbakeman]

I'd like to suggest a few changes be made to the Projects page to bring it up to date as best as I can find.

• KNutClient: Last available version of the website seems to be from October 2020. It doesn't seem to be in any other live locations besides Ubuntu and Debian distros. Move to Legacy section?
• NUT-Monitor: Last update in 2010 - move to Legacy?
• Windows NUT Client/winnutclient: Accurately stated; the original client on Windows! Consider moving to legacy section?
• WinNUT-Client: Accurate description, but please update to the latest URL. I haven't been able to contact @gawindx in years so I've forked in and continued development. I'm also working on a set of .Net libraries in the same organization for interacting with the NUT protocol (both from a client and mock-server's point of view) if that's at all interesting.
• WinNUT: Perhaps the primary description can be distilled down to the mention that it's currently being worked on by the main networkupstools organization, and link to that. If desired, perhaps the history can be moved down to the legacy section.

Setting up an environment to make and test changes myself seemed a little daunting so I'm not sure I can get to this straight away, but hopefully this is helpful as a starting point.
