SCSS: remove punctuation from classes & identifiers

Prevent appended pseudos as well. This should make the tags file output
more consistent with other language parsers, where the identifiers are
more important than the delimiters that denote their types. This aids
completion in existing tools and across languages (like HTML) where the
delimiters are not used.

Closes #3409
