Title: Add hide support to tab widget

Adds preliminary support for hiding the content area of a tab widget by
means of toggling the content area to "hidden" if the selected tab's
content area is already visible when it is clicked.

This probably needs more work to be generic/flexible enough (maybe an options variable?) but it works and certainly seems like a useful feature.
