Using button meta

NOTE: All strings replace these variables:

%streamer%: Replaces with the user name of the person running the command
%presser%: The person who pressed the button
%SSL%: Space separated list of players that pressed the button
%CSL%: Comma separated list of players that pressed the button
%HRL%: Human readable list of players that pressed the button (adds in an and, also removes duplicate pressers)

What's the difference?

A button's meta is basically what tells the button what to do.
Every button can have a type meta tag and a action meta tag.

Here's a list of each type and what they do.
Working:

summon:
  action: minecraft:mob
  NBT (optional): The mob's NBT data
runCommand:
  action: full command without slash
runCommandAsServer:
  action: full command without slash
switchWindow:
  action: name of scene to switch to

Planned:

move:
  action: Takes either forward, back, left or right as a string
look: #It is just applied to a joystick, the action isn't needed on this one
