Added ability to copy schedule links

[Malorn44]

It's not fully working. But the basic functionality is here.

What is working:

• Schedule link copying
• Replacing selected sections
• Keeping selected sections

What isn't working:

• A temporary schedule will always initialize to index 0 even if another is specified.

I don't know exactly how to fix this yet, but I do know the issue. The line that I need for setting the index isn't running when it needs to be run. I was able to fix this by putting in a timeout but that is way too slow. Going to expand on this later to add that functionality, but for now I feel it is more important to have at least this out there to be used.
