Add option to remove close buttons on tabs

Please add an option to remove close buttons on tabs. Many people dislike them because they make too easy to accidentally close a tab.

I am in the camp of the opposite and feel if an editor does not have a close button it is simply not an editor at all. But i agree with you that an option should exist under preferences to hide it for the minority who may want it. But by default it definitely needs to be shown.
