Add option for word wrapping in Edit Database Cell

A new option, in the toolbar of the Edit Database Cell, is added for
setting word wrapping for the text editor modes. It is now independent of
the SQL preference. The configuration reading the editor/wrap_lines setting
is moved to the particular SQL editor class.

Added icon from the Silk icon set.

See issue #1796
