Tristate toggle

fixes: #1671
see issue for details.

you can review first 2 commits individually:
1st- added extension for UIHelper to ensure type safety and convenience.
2nd- Added interface to propagate option dependencies (E.g.: enter blocked junction depends on junction restrictions).
this used to only work with checkbox but now it also works with tristate checkbox.

other commits:
- Created tristate toggle option
- if user moves mouse over the tristate sprite, tooltip is `yes no N/A`. 
but if user moves mouse over the text label, the tooltip explain what the option does.

Test:
I tested propagation of dependencies also work.

You need to type test code like the one I gave you on discord. also attached a test code in the description of this PR

What do you want to test?

[kianzarrin]

should I squash these two commits to the second commit and force push?

this way all commits relating to propagation can be reviewed as one commit.

I want to see where this is used. Are you merging unused code?

[kianzarrin]

Are you merging unused code?

yes. next step is cleanup roundabout/high priority polices but that would be too much for this PR.

Tested with example code, seems to be working ok, but it is not disabled in the main menu as the other checkboxes

[kianzarrin]

@krzychu124 fixed disabled color
