Update to .NET 6

[wiggleforlife]

See Nikolai558/NASR2SCT#127
Pretty much the same as my previous PR, except:

• Updated to .NET 6 instead of 5 (requires VS2022 or another IDE that supports it)
• Includes a Squirrel fork

Microsoft aims for a .NET MAUI RC in Q1 and a final release in Q2.

Changes

• Ran the .NET Conversion Assistant
• Removed old imports and the App.config
• Added an application manifest to the UI for the Squirrel packing system
• Replaced Squirrel.Windows with Clowd.Squirrel
• Added a function to create the desktop and Start Menu shortcuts
• Rewrote instructions to publish a release

This looks good!

I would be willing to pull this into the dev branch as soon as you mark it completed. The only thing I would want to test and verify is the Updater (from framework to core) as well as (core to core)

[wiggleforlife]

I believe the updater works from Core to Core, but I have seen a potential issue (clowd/Clowd.Squirrel#9) with Framework to Core. I'll hopefully finish it by the end of the week andmark the PR as completed.

Just a note about Clowd.Squirrel and updating from Framework to Core, this should work from a Squirrel.Windows->Clowd.Squirrel perspective, but there is additional consideration about managing the new runtime dependency.

You can publish your app as self-contained if that's suitable (thus bundling all your required dependencies) or alternatively, take care to install .net 6 yourself (using the new Squirrel runtime API's) before updating to a version that requires it. If you choose to do the latter, you should ship a release on Framework using Clowd.Squirrel as described in the issue you linked before updating to net6.

Regarding the missing shortcuts, at the top of Program.cs, you need to add SquirrelAwareApp.HandleEvents(() => new UpdateManager(null).CreateShortcutForThisExe()) or similar.

Another note about Program.cs:StartNewVersion() is that you can use UpdateManager.RestartApp() to automatically restart the latest version of the currently executing binary.

@wiggleforlife I have taken a stab at making some improvements in my branch here https://github.com/caesay/FE-BUDDY/commits/dotnet6 - there is only two things todo yet, which is to write a build script that trims the publish assemblies (eg. WPF) so that FE-BUDDY releases can be smaller, and get delta updates working. I'll have a look at this soon.

@caesay Thanks for all of this, you're being an absolutely massive help. I was going to look into replacing this with Squirrel's GitHub update system as well in the future, but since you're already doing it this makes everything a lot easier. Thanks again!

These are amazing changes, thank you both for your help with this. I have created pull requests to move it into the dotnet6 branch on my repo. I will probably merge that branch into dev then release a new version here soon.
