Add feature to resize columns automatically

Revert capability to double click on the line between two column
headings in a Browse pane to cause the column to be sized to fit
the data.

Previously, the column resized just wide enough for the
widest single character.

Modify column resize for content width only

The previous fix resized the column for the maximum size
of header width and content width.

This behavior is now only applied for content width.
