If the form is opened via a grid field, the filters will be retained so the previous/next record opened will be correct

GridField doesn't have a valid readonly state if it's value is set to an Object
without `forTemplate()`. The default behaviour is to render a ReadonlyField,
but given GridField is a complex type this isn't suitable.
This bugfix provides a transformation method to render only components that are
whitelisted to provide a readonly state.
@see #3357 - https://github.com/silverstripe/silverstripe-framework/issues/3357
Print view uses the SilverStripe templating to render values which means that
values are safely escaped by default. This can be tested by chaing `$CellString`
to `$CellString.RAW` in the GridField_print.ss template to see this escaping
being disabled.
This pull request removes double escaping of HTML in strings.
