The `TopMenu` methodmap natives weren't marked as optional if the extension was optional like the other normal natives.
The `Regex` natives weren't marked as optional at all before if the regex extension was included optionally.
This makes the error message cleaner in case topmenus aren't loaded.
```
adminmenu.smx (Admin Menu): Required extension "TopMenus" file("topmenus.ext") not running
basebans.smx (Basic Ban Commands): Native "TopMenu.Display" was not found
```
