A new column for a Javascript action

[AndrewCRMartin]

A new option to add a 'highlight' column of buttons. This option would be associated with a piece of JavaScript that is run when the highlight button is clicked - the programmer can use this for whatever is required. In our case it would take an ID associated with the row and use this to highlight a row in an associated table with linked IDs (something like ID=xxx, table ID = tab_xxx).
