Implement Display scoring support

[jsm174]

This PR is to support freezy/VisualPinball.Engine#421 and freezy/VisualPinball.Engine#435.

It adds the following units:

• ClearDisplayUnit
• AddPointsDisplayUnit
• DisplayScoreEventUnit

ClearDisplayUnit

This unit can be used to clear a display. For a ScoreReelDisplayComponent, if it is connected to a ScoreMotorComponent, the reels will be advanced in a sequence.

For example, if the score is 4805, the score advance sequence will be: 5906, 6007, 7008, 8009, 9000, 0.

AddPointsDisplayUnit

This unit accepts an incoming points amount, and if the display is connected to a ScoreMotorComponent increases the score appropriately. For example, if the points are 500, and the Score Motor is not running, the score reels will be advanced 5 times, (100 points per advance).

DisplayScoreEventUnit

This unit receives updated score events from the connected display. The score can then be saved into a Player variable, or used to drive an additional display.

Since only ScoreReelDisplayComponent can keep track of scores, we needed to add a Display Type to Visual Scripting Displays:

After discussions on Discord, @freezy suggested using the existing Update Display unit instead of an additional Add Points unit.

I've refactored the code accordingly, and it really makes everything a lot cleaner.

We are now only adding two nodes, Display Update Event and Clear Display.

Display Update Event triggers when the display has been updated. If the display is a Score Reel, it will have a Numeric output which is the Score Reel's internal score. This internal score can then be used to set the player's score variable.

Note, the internal score may be greater than the amount of reels.

Here is an example of updating reels, capturing the score, and then sending that score to a segment display:

The Display Type setting that was added to Visual Scripting Displays has been removed too.

@freezy when you have free time, can we get a Display Update Event icon with the lightning bolt?

Looking good!

I guess now we need an "interruptor" node so we can turn off some lights in Volley when the motor is running?

[jsm174]

I think we can look at the motor running switch to accomplish that.

Yes, the interruptor would take in the motor switch and the light status and its output is then wired to the light.

[jsm174]

Interesting. I was thinking of just taking the lighting graph and toggling the specific light variables volley uses.

That would be a useful unit.
