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
```
Various minor things done to project files
Updated sample extension project file and updated makefile to the new unified version (more changes likely on the way)
Updated regex project file and makefile
