Replace "eval" method

[Speravir]

Starting with Firefox 70 every script with "eval" will by default cause Firefox do not work at all (there is a config setting for developers, but this really should be used only when testing). Some of your scripts do use this.

A tip in a forum was to insert the eval code part into the browser console and copying the output (with some cleanup). Using this approach I was successful with some other scripts, but not with your scripts, especially in UndoListInTabmenuToo.uc.js where eval is caling a variable inside this variable.

UndoListInTabmenuToo.uc.js case, use JSON.parse

Thanks for your updates I noted only now. I do not close this issue because I do not know whether you fixed all scripts. As the repo owner feel free do close it yourself.
