Enables proper indentation via CSS
Each text snippet gets an additional class tag of the form
nesting-level-1, nesting-level-2`, etc. It can be used in CSS to define indentation:I am not sure this is the best way to implement such a feature. It ought to be done for all snippets, not just text snippets, but there doesn't seem to be a good place in the code for that.
