Allow user to set the BLOB text. Preview for field display in Preferences

Browse Source 
A new setting allows the user to set the text for BLOB data in the cell.

The existing line-edit for setting the NULL text and the new one for BLOB
are updated with the cell background and foreground colors, providing a
preview of the desired changes. An additional preview-only box is added for
the regular fields.

See issue #1263

Settings in Database tab are left-aligned for consistency to other tabs.
See comment in #1173.
