Previously, the payment button was larger than the others and next to
the numpad. The other buttons were managed by a mixin and arranged
in a predefined order.
Now, the payment button only stays in place when the "order" button is
not present, currently it can only be present if the restaurant module
is installed and a printer configured.
When it is present, it takes the place of the payment button and the
latter is added to the mixins with the other buttons
