Bugfix: Number of visible items was not set properly, because of using height(). Now outerHeight(true) is used to calculate true height (including borders and margins) of an option.
Bugfix: On expose settings form, 'all display' mode was not saving SE settings for first.
Added new configuration option: width. Thanks to mr.york for his suggestion about 'px' field suffix.
Changed to Views module's #dependency feature from core states.
