Summary:
Added a new object type code `l` (for lookup) which can be used in user actions as a temporary cell value in ref[list] columns and is immediately converted to a row ID in the data engine. The value contains the original raw string (to be used as alt text), the column ID to lookup (typically the visible column) and one or more values to lookup.
For reflists, valueParser now tries parsing the string first as JSON, then as a CSV row, and applies the visible column parsed to each item.
Both ref and reflists columns no longer format the parsed value when there's no matching reference, the original unparsed string is used as alttext instead.
Test Plan: Added another table "Multi-References" to CopyPaste test. Made that table and the References table test with and without table data loaded in the browser.

Summary:
Handle reference columns in ViewFieldRec.valueParser.
Extracted code for reuse from ReferenceEditor to look up values in the visible column. While I was at it, also extracted a bit of common code from ReferenceEditor and ReferenceListEditor into a new class ReferenceUtils. More refactoring could be done in this area but it's out of scope.
Changed NTextEditor to use field.valueParser, which affects numeric and reference fields. In particular this means numbers are parsed on data entry, it doesn't change anything for references.
Test Plan:
Added more CopyPaste testing to test references.
Tested entering slightly formatted numbers in NumberFormatting.
