 Bugfix: avoid empty tooltip with multiple fields

 This patch makes ToolTipControl behave the same way with multiple
 fields like it does for a single field. If ToolTipControl is activated
 for a VisualItem, which has other fields than the ToolTipControl
   expects, it won't have any text to display in the tooltip. Therefore,
   it
   should not even show the tooltip.

 Bugfix: ranges on double and long values correctly mapped to int

 When you work with a NumberRangeModel that is initialized with double
 values, setting the value range with the method setValueRange() yields
 an unexpected result (a tiny range close to the minimum is selected).
 The bug is in updateRange(), where the double range is transformed to
 an
 int range from 0 to 10,000. The problem is that the multiplication with
 10,000 happens *after* the intermediate result is converted to int. So,
 v and e are either 0 or 10,000.
 The same bug and patch should apply to NumberRangeModel that are
 initialized with long values. (I did not test it.)
 NumberRangeModel that are initialized with int values are not affected
 by this issue, because they do not need such an transformation.

 handle cascaded columns when they are removed from the parent table

 If a column is removed from the parent table of a `CascadedTable` the
 listener calls `filterColumns(...)`. There `Column` objects for all
 indices of `m_pnames` were retrieved, which resulted in a
 `IndexOutOfBoundsException`.
 Now, `Column` objects are retrieved by name and checked if they exist.

 Bugfix reversely sorted iterator. Member "reverse" was not initialized.

 If you use the method table.rowsSortedBy to iterate over table rows in
 a
 descending order according to some column, as follows
 IntIterator sortedRows = table.rowsSortedBy(COLMUN_VALUE, false);
 only one row will be retrieved by the iterator.

 The problem lies in the inner class EntryIterator, the field reverse
 which specifies the sort direction does not get assigned in the 1st
 constructor.
