[Feature Request] New property "excludeAppFolders"

[cegekaJG]

I propose a new property for .AL-Go/settings.json called "excludeAppFolders". As the name suggests, it allows developers to exclude folders from being seen as an app folder that would otherwise match.

This can be useful when a project either has a large number of apps and only wants to skip building one of them, or if a project with an excluded app might have additional apps added in the future, and developers don't want to update the "appFolders" property every time they do so.

This could be applied to all other lists of folders or glob patterns such as "testFolders", as allowing the user to exclude matches is very common for configurations.
