The `Orderline` model contains the fields: `price_manually_set` and `price_automatically_set`.
They are meant to signify what type of price the orderline has: `automatic`, `manual` or `original`.
It's very confusing to manage the two fields when in fact they only describe three types of setting the orderline price.
This PR replaces the 2 fields with a single one: `price_type`, which will take one of the 3 possible values.
