Enable restart button if no one wins playing

Restart button by default is disabled. Currently is enabled only when a player wins. Need to enable it if game ens up in draw.

Hi I would like to solve this issue

I have submitted a pull request for the above issue.
While I was looking through the code, I noticed an issue with player X.
There's a specific condition if player X wins diagonally then it wont reveal the rematch button and the game wont end

If you want I can fix this issue as well and add onto the previous commit

Okay please fix the diagonal issue also. Actually in logic i have taken care of that condition also but I think its due to some small syntax or logic mistake the diagonal is not being recognized. In my testing I actually missed this condition. Thank you for finding it.
I am opening a new issue for it.
