BUG: Edit an old post but displays "Reply to" a subject

[Migrated From Jforum.net]

The post_form.htm has a bug on distinguishing from Edit and Reply to and old post. Just add the isEdit check and the I18n key PostForm.edit to fix it:

<#if forum?exists>
  <#if (topic?exists && topic.id > -1)>
    <#if isEdit>
       ${I18n.getMessage("PostForm.edit")} "${topic.title}"
    <#else>
       ${I18n.getMessage("PostForm.reply")} "${topic.title}"
    </#if>
  <#else>
    ${I18n.getMessage("PostForm.title")}
  </#if>
