From 9d88ca13b9b6a193dfb17a1ee3ea5e5cbed8a7e9 Mon Sep 17 00:00:00 2001
From: Thomas Tanner <trtanner@btinternet.com>
Date: Thu, 15 Oct 2015 13:34:01 +0100
Subject: Added functionality to use the web page link in a fomod to supply an
 optional web page.

Also refactored modinfo into multiple files (as the actual types are opaque anyway) and cleaned up the headers a bit

I also changed 'visit on nexus' from the menu not to open the downloads tab because it was a little confusing
