Describe the new feature

This new feature should encompass a method called deleteDirectory that can be used to delete an entire directory including all its contained files from a given template.

Why do you need this feature?

Currently it is only possible to delete singular files from a template.
This works fine but may leave empty and unused directories behind.
In addition to that, deleting entire directory trees is very inefficient when deleting each file separately.

Alternatives

The only other way of removing the remaining directories would be to manually delete those files.
Developers of modules cannot do that and would need to instruct an administrator to do this. This would leave developers at the mercy of attentive administrators/users.
