This reduces chances of errors where consumers of strings mutate inputs and reduces memory usage of the app. Test suite passes now, but there may be some stuff left, so we will run a few sites on a branch prior to merging
Widgets can now specify a template which is precompiled using Glimmer's AST and then converted into our virtual dom code. Example: ```javascript createWidget('post-link-arrow', { template: hbs` {{#if attrs.above}} <a class="post-info arrow" title={{i18n "topic.jump_reply_up"}}> {{fa-icon "arrow-up"}} </a> {{else}} <a class="post-info arrow" title={{i18n "topic.jump_reply_down"}}> {{fa-icon "arrow-down"}} </a> {{/if}} `, click() { DiscourseURL.routeTo(this.attrs.shareUrl); } }); ```
