Execute store entity and data modify entity would affect players

This would add far too many new possibilities to list, but among them are, putting a player's velocity in a certain direction, changing the length of effects, giving them some of the capabilities of creative mode without giving them it directly, giving players NoGravity, and teleporting them to locations chosen by the output of another command. This would be done like it is done in entities, or the inverse of what execute if entity or data get entity do.
