Changed the way the FilteredCardList on the stats panel selects cards:

used to: by running scripts on cards and comparing to string value of selected group
  now:     by keeping a list of group_ids for all cards, and comparing indices
Added 'bin size' attribute for making a histogram of numeric axes.
Added 'Text length' statistic.
