function commerce_reports_views_pre_build in Commerce Reporting 8

Implements hook_views_pre_build().

For all price fields, ensure that our PriceNumericField handler is used instead of the normal NumericField handler. This ensures proper formatting of the currency.

This assumes the currency code is available, by having it set to GROUP BY and not being aggregated by a function.
