Make "Action Button" non-exclusive for player event

[Br4ssman]

This proposal is versatile for many things that are only dependent on the player event.

The aim of this proposal is to move from the Trigger "Action Button" to "Action Button [Select Event]", as often the player event is a simple camera outside the play area and the real player is a normal event controlled by key input proc.

Perhaps it would be even more interesting to do it in a different way so that it is not exclusive to a single event, but that the trigger can be done by selecting one or multiple events and all of them would respond to this trigger if the case arises;
"Action Button: [Select Event], [...]"
