Fixed misplaced bracket in _view/fields-values
_list/tabulate no longer requires strings to match exactly.

This is way better than before. And String.search() accepts regular
expressions, so this covers pretty much everything. I also removed the
case-sensitivity because I can not think of any realistic use-case right now. I
might adopt the pentadactyl 'smart case' model that assumes case-sensitivity as
soon as there are both upper and lower case letters.
Treatment of numbers is still horrible because they are just converted to
strings.
