disable PlaceButton script

Not sure when it was introduced, but a script is running PlaceButton() to position the CO2 button above the checkout button on window resize, changing the position to absolute and the width to match the Checkout button.

This might work for some themes, but gives very undesirable results for ours:
the Checkout button is pushed off screen and the CO2 button width is too small.
Users cannot make any buy on mobile screens because of this issue.

There should be an option to turn this ‘feature’ off. The initial place it gets rendered to is fine and there’s no need to any repositioning by script.

We had to disable the plugin.
