Export raw values by default, optionally process tokens

Problem/Motivation

A current problem is that tokens are processed while the tags are generated. This means that if the spreadsheet is imported again it will erase any tokens present in the field values with the raw values, which means those values would then become harder to manage over time.

Proposed resolution

By default just output the values from the field.
Provide an option to output all values that could be rendered for a specific entity.

Remaining tasks

Build a patch.

User interface changes

By default just output the values from the field.
An option would exist on the export form that would output the final rendered values.

API changes

TBD
