add tooltip to cells if 'truncate' variable is set

If a Column has the 'truncate' variable defined, we should
have a tooltip to show the full text if user hovers over
a cell. For example, Project > Volumes Description column is
truncated at 40 chars. 'Truncate' column attribute should be
used on Strings, not Integers, fixed test case.
