Subject: [PATCH] Automatically removes leading and trailing spaces from tags
 because tags are often entered with a space after each comma. This uses
 .trim() in func.render_tags() to remove when rendering as well as .map(str =>
 str.trim()) when a post or post edit is submitted so they are also stored
 without spaces.
