Fix layout of quicksearch preference page

The multi-line preferences for ignored names/prefixes/extensions do not
resize and therefore have a different size than the maxLineLength
preference at the top of the page.

Remove the character width limitation, and set a layout data width
instead. This makes the field editors resize as expected, such that all
field editors have the same size.
