Implement a column that display "External name" for samples, extracts and derived bioassays

[Nicklas Nordborg]

For items that have an "External ID" directly on them (eg. Patient, Case, Specimen, etc) the external ID is used directly. For other child items the parent item should be located and the internal SCAN-B ID should be replaced with the external ID.

It should be possible to export the column.

It would be nice if the column could be filtered but this may be difficult since we are combining values from different tables.

Added an extension for the "External name" column. We need BASE 3.19.12 since we want to set a different export title.

Changed the output in the column so that it is only the external ID that is linked and the link goes to the parent item (eg. Blood or Specimen).

Implemented support for filtering. The filter will ONLY work on the external ID part of the name.

Add a help message that is displayed when a filter is causing no hits.
