[MMO] Rename Attachments 2.1.3

The add-on allows you to add a prefix to attachments. For example, the attachment is called mmo-zone.info.zip, and after installing this plugin we can add any prefix to the name and it will look like this: [mmo-zone.info] mmo-zone.info.zip

• Works with all attachments that are laid out on the forum

• I also wanted to express my gratitude for the idea with the postfix @ozzy47
