Core: Silently fix invalid yaml option for Toggles

[ScipioWright]

What is this fixing or adding?

When the user puts in an invalid option for a Toggle, it fails at the end of gen with a very unhelpful

Traceback (most recent call last):
  File "__startup__.py", line 124, in run
  File "console.py", line 16, in run
  File "Generate.py", line 549, in <module>
  File "Generate.py", line 240, in main
  File "Main.py", line 442, in main
  File "BaseClasses.py", line 1377, in to_file
  File "BaseClasses.py", line 1360, in write_option
  File "Options.py", line 137, in current_option_name
  File "Options.py", line 397, in get_option_name
IndexError: list index out of range

Now, it'll just convert it to something valid.

Previous PR: #3098

Easy way to reproduce the error:
Grab a Clique yaml, set the Hard Mode option to 4

How was this tested?

Tested by picking a yaml, setting a Toggle setting to something greater than 1, then seeing it not error out.

If this makes graphical changes, please attach screenshots.

since bool is a subclass of int, that last call isn't stricly necessary, but I think it's fine here to make the intention clear.

I do wonder if loudly fail would be better though; time will tell.

[ScipioWright]

Yeah, we'll have to see. I think it should be fine?
