Code style: file scoped namespace

[brmassa]

Newer versions of C# allow file-scoped namespaces. Instead of creating basically double brackets to accommodate namespace + class.

using Sytem;

namespace Prowl 
{
    public class MyClass
    {
        public void MyMethod()
        {
            DoStuff();
        }
    }
}

become

using Sytem;

namespace Prowl;

public class MyClass
{
    public void MyMethod()
    {
        DoStuff();
    }
}

Advantages:

• Less indentation
  • easier to read on Discord or narrow chats
  • most IDEs try to split lines above 80 character
• Cleaner code
• Most of the conversion is done only once

Disadvantages:

• HUGE diff when updating all files, since most of the code base was using the old style. The commit will alter basically all lines of all files.

---

Because one might be annoyed, it's recommended to do during a big rewrite of the code, like the current development branch. I suggest to each developer to express opinion.

Tasks

quite simple

• [x] Convert all files to file scoped namespaces
• [x] include a rule inside .editorconfig to raise warnings when using normal brackets

Im down for this, The reduction in Indentation would be nice. Especially for UI stuff, since the UI API generally results in very long lines.
