Changes

MGS 1: support for the new and shiny 64-bit version of the game! (Ver. 3.0.0)
- This doesn't include support for modding any of the new systems/etc. introduced in Ver. 3.0.0. This is a compatibility release; future releases will explore mods and fixes specifically for the upgraded game.
- Specifically of note is the widescreen hack currently does not work in the "high resolution" or "full resolution" modes, so if it's enabled it will be ignored.
More games supported:
- Gradius Origins
- Operation Night Strikers
Added mod version checker - by @ShizCalev.
Force game to run on dedicated GPU where a separate integrated GPU exists - by @ShizCalev.
Fix for monitors going to sleep during long periods with no input (e.g. during cutscenes) - by @ShizCalev.
Add warning if Windows background shuffle is on due to observed cause of poor performance - by @ShizCalev.
Add MGSM2Fix.ini option to disable Windows fullscreen optimisation, fixing main menu corruption issue on some systems - by @ShizCalev.
