Request: shortcuts for checking box and "patch game" button, and more

[dgdg123]

I like to speed up the game 500% when I die in a boss and gonna have to wait 30s in the "you died" screen, plus loading, plus walking from the check point to the boss room and slow the game back to the default speed when I enter fight is going to start. Its a pain in the ass to do that right now, some shortcuts for those options would be amazing.

the "disable camera auto rotate on movement" worked but I cant disable the feature after I enable it. The box is unchecked, I patched the game but the camera behavior still is "patched". Tried to close the game and reopening it and didnt manage to revert the game back to the default camera behavior. I will check a bit more and post here if anything changes about that.

This PR should fix the camera auto rotate disable not working: #111

For my own use, I've hacked in a hotkey to toggle the game speed adjustment. The diff is below (although it won't apply automatically with patch due to unrelated factoring I did nearby). If there is interest, I could make the key customizable and submit a PR.
