js: refactor and simplify @mentions handling - no functional changes The autocompleteCreate and get_mention functions are inlined. The mentionQuery and tuple in datasource are replaced with before/search/after data attributes on the $container element. Variable use is simplified - less variables, better naming, and better content. The @ is now in the before string, not in the search string.
