This has the advantage of being self contained (doesn't conflict with Unity 3.x - 5.x loader, so we can use the original one) and **disabling auto updates actually works**.
We can also eliminate any code used to install and verify unity, since it's all self contained.
Also added fusion manifest file to set process as DPI aware, and set ACP to UTF-8 on Windows 10 1903 and above.
Bumped version to 1.4.2
**Formatting going forward**
Variables: camelCase (capitalization of two letter abbreviations is OK, e.g. playerID)
Classes: PascalCase
CSS: kebab-case
Files: kebab-case
**Other miscellaneous changes**
* The WebPlayer crashing as well as failing to load the config file are now fatal errors and will quit the app
* Moved some style attributes from index.html into openfusion.css
* Hoist everything into a function
* Add error handling
* Rename vars for clarity
* Skip renaming if the current and new version are the same: this along with the error handling should fix the black screen when using multiple clients
