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.
