gridsort: allow inserting columns into the column model while the control is already alive (unfinished)

Missing: Adjustments to the data model. Probably we need to change the API here: It does not make sense
that the only method to retrieve actual data from the data model is "any[][] getData" - this doesn't scale
at all, and blocks all dynamic changes to the columns. I suppose we need some "any getCellData( col, row )"
here.
