Whilst working on [Create endpoint to generate fake data](#347) we added a number of formatters. These take data from the DB and re-format them to match how the UI displays the values.

We believe we are going to need these formatters in future changes we'll be making, the first of which is a re-designed bill run page.

So, to help prepare for that we are adding those formatters to our `BasePresenter` so they are available to any future presenters we add.
