Add comment in System log action

[Endercraft]

This action would be useful, especially for long macros that have loops ; a lot of the time it's hard to understand where you are in logs of such macros. So that's why I suggest adding a "comment" action, that would have a different, easy to see color to distinguish and maybe a different police. For example :
Empty trigger
Invoking macro : Comment action
Popup Message (popup)
"This is a comment from comment action"
Popup Message 'Constraint' did not invoke because constraint failed : Battery < 0%
