Fixes#3017
Thanks to Hercules for the idea and their implementation of it.

Since 64bit ticks do not exist on XP, you might encounter some issues that are already fixed on other OS.
* Resolves PvP timers and effects not displaying properly.
* Resolves any GvG effects not displaying properly.

* Alphabetically sorted includes.
* Updated copyright and license text to match across all files.
