#77 dynamic End of Turn button

[paroov]

End of Turn button creates a trigger for end of turn.
There is a problem with it:
sometimes I want to use it, but i change my mind later.
The trigger stays active and i can't cancel it. Thus my
opponent knows, that i wanted to play smth eot.
example:
i have 2 cards (counterspell and Thirst for knowledge)
4 islands on the table
i pass the turn to my opponent and click the eot button
(cause i want to acst TFK eot). Opponent casts smth, i
Counter it with counterspell, so i don't have 3 mana left
for TfK. At the end of turn the trigger will appear, and
my opponent will know, that I wanted to play an instant
eot. Thus - he knows that i do not have another
counterspell in my hand.

solution:
EOT button toggles the trigger. Once clicked -
activates, next click deactivates it. Current trigger state
is shown by different graphic for the button (changed
colors or any mark on it)
