/**
* widget for displaying a single notice
*
* This widget has the core smarts for showing a single notice: what to display,
* where, and under which circumstances. Its key method is show(); this is a recipe
* that calls all the other show*() methods to build up a single notice. The
* ProfileNoticeListItem subclass, for example, overrides showAuthor() to skip
* author info (since that's implicit by the data in the page).
