Create buttons to add/select new road before/after roadpoint

[bdog2112]

This work is, for the most part, complete!

What's working:

• Add/Sel/Prev/Next buttons show/hide as expected
• New RoadPoints are created/copied from existing
• New RoadPoints are automatically selected
• New RoadPoints are placed 4 lane widths from previous
• New RoadPoint names are automatically incremented (with some limitations)

What proved challenging:

• Accessing the "Scene tab" from the Inspector panel
• Populating RoadPoint lane and traffic arrays
• Getting RoadPoint magnitudes to work
• Getting new RoadPoints to show up in Scene tab

What requires additional work/research/troubleshooting: Naming algorithm needs evaluation. See additional notes further below.

Monthly time limit has been reached.

Regarding node naming requirements:

We know that Godot will auto-increment numbers at the end of a name. Hence, in the simplest scenario, we could forego doing any special name processing and let Godot do the work.

Conversely, we could go high tech and employ regular expressions to search for numbers in the middle of names with the caveat that there could be multiple numbers and complex scenarios that might be hard to support. We would also need to define the supported and non-supported scenarios.

I propose the following simple and sustainable approach:

• If a name ends with an integer, then just keep the existing name. Godot will increment it.
• If the last character is not an integer, then add "001" to the end of the name. Godot will increment the name when needed.

Examples:

Input: my_road01 Output: my_road02, my_road03, my_road04

Input: my_road Output my_road001, my_road002, my_road003

Input: my_#1road Output: my#1road001, my#1road002, my#1_road003

Thanks for detailing out these options. Will get to the code review tomorrow.

Regarding node renaming: let's not go crazy with that, it was a minor note that I was just hoping we'd do a simple solution for. The utility of the other tasks are higher, so I can live with what we have for now.

edit: said differently, I support your solution as it's using part of what Godot already does, and your addition to just add a 001 if needed works fine 👍
