"Reload level" button patch for the executable

[slothybutt]

If we could reload the level in LH without saving, that would be super, super helpful, either via an "exit without saving" option or by a "reload level" ability. This has some problems, being:

• This would probably be quite hard to implement, adding things is probably a lot harder than changing one specific thing
• This could be dangerous for normal editing, if you accidentally hit some sort of reload keybind, or exited without saving, the level would be reverted back to its last autosave. The only ways I can think to 100% failsafe it seem complicated. You could have the option to revert the reload, maybe you could try to figure out whether the incoming file that you want to reload has been edited, somehow, or give the player the option to choose what version of the level they want to keep as an extra precaution.

This would be hard to add, but cool to see.

This isn't possible with my current understanding of the Levelhead executable, but I'm leaving the issue open in case it becomes relevant in the future.
