Copy&paste should also copy the row names for DoubleArrays

r14299: also added row names to clipboard for StringConvertibleArrays (the code for copying to clipboard was irrelevant anyway because C&P was not disabled for the DataViewGrid)

I get an exception when I try to copy and paste from a StringConvertibleArrayView. Maybe this change is responsible. It's a bit strange, because it's 4 months and no one noticed. But r14299 is the last change on the view. Please have a look.

The problem was that Content.ElementNames need not be defined for all string convertible arrays. Also only the copy to clipboard code was manipulated and not the paste code which broke copy&paste from and to string convertible arrays.

The logic of correctly parsing a clipboard text with or without element names is unfortunately all but simple. Previously we had support for pasteing row vectors, because we included both tab and newline as separators, which is functionality that should be retained.

r14561:

• Corrected copy & paste from StringConvertibleArrays
  • There are four possible cases that are handled by this change (rows are newline separated, columns tab separated)
    1. There is just one column of values
    2. There is one column of element names and one column of values
    3. There is one row of values
    4. There is one row of element names and one row of values
  • A message box is shown if the user selects a 2 by n or n by 2 range with n > 2
