Created a seperate actionlist to document actions

In documenting the huge list of actions available, the list got rather large. I felt it was a good idea to separate this list out, sort them by category, and add a TOC. Action.md now links to actionlist.md instead of having the list embedded.

Wow, that must have been a ton of work. Thank you, you're amazing 👍! (obviously, I can't check if the actions you documented are correct before merging, but looks good so far)
