Re-implement input history #602

[kiralydavid]

• Added input history as a new add-on.
• You can toggle it on/off from the web-config.
• It's possible to set the length of the history string (in characters) and position it on the screen by setting the starting column and row.

This looks great! Thank you @kiralydavid

I will test this out when I have some time. Are you on the Discord?

Documentation piece looks good.

Thank you for following the template. Though, if you could include the ### Installation header and just put "None." beneath so as to maintain consistency with the template and other documents.

A few minor adjustments I'd make, just for the sake of following the existing code patterns.

• I understand the reasoning for doing it, but try to avoid changing the pattern on addon constructors. Creating the Display addon should not require the Input History addon, even if it's disabled.
• Instead, I would suggest adding a method on the addon so we only have to attach the two addons if they're enabled. It should ultimately be optional.
• Check the state of both Input History and Display in your available() method if the Display is not enabled. See the Wii Extension addon available() for a means of doing this.

Code changes are looking good on my end. Nice turnaround!

@kiralydavid Looks great! We just had a push to our i2c peripherals, could you pull latest and resolve conflicts on your end? Should be pretty straight forward, @mikepparks did a great job on the i2c stuff.
