Use same file layout as Atelier

[mvhenderson]

This extension exports files using a file type prefix directory (e.g. CLS). Atelier only includes this prefix for CSP files. While this works when adding a project to the Atelier workspace, if you create a new file in Atelier it doesn't use the prefix.

Reproduce:

• setup a VSCode workspace with a class, for example:

      1 example
      2 ├── src
      3 │   └── CLS
      4 │       └── User
      5 │           └── Test1.cls

• In Atelier, create a workspace pointing to the example directory, then add a project for the src directory
• Everything should work fine with User.Test1.cls - Atelier imports the code, changes are reflected both on the server and in VSCode
• In Atelier, create a new class User.Test2.cls
• Notice the class is saved to example/src/User/Test2.cls
• Again this works fine - User.Test2.cls changes are reflected in Atelier and the server however the filesystem paths are off.

Observed Behavior:
Atelier by default creates classes to <workspace>/src/<package>/<name>.cls
VSCode by default creates classes to <workspace>/src/CLS/<package>/<name>.cls

Desired Behavior:
Atelier and VSCode use the same paths when creating classes, routines, includes and CSP.

@mvhenderson it does indeed looks like the CLS is redundant unless VSCode creates an RTN subdir and a CSP subdir etc. I don't know how those are groupped up. it'd be useful to be consistent in the grouping.
What are people's thoughts on this?

I've added new setting objectscript.export.addCategory boolean,false by default,
when true will have the previous behaviour,
when false, as you suggest, without this category folder
