Cell selection is independent of item selection.

Cells are identified with a two element list with item id and column id.

A new subcommand **cellselection** is added, mirroring the present **selection**.
In addition the **cellselection** commands get
a version with two arguments for selecting/modifying a rectangular range.


Since for **selection** the itemList can also be a single item (by nature of
how lists work for simple values), this is also allowed for a cellList since
a two cell list can be clearly distinguished from the two element list that
is one cell.

Only cells in displayed columns are allowed to be selected. Any change to
**-columns** or **-displaycolumns** clears the cell selection to avoid
ambiguous state.

A new option **-selecttype** *type* is added to direct default bindings to
use either item selection or cell selection. It takes values `item` or `cell`.

The **identify** subcommand is updated with the **cell** option.

Default bindings are updated to use these features.
