 * Uninstall handler for ABCode Improved Caching for 20i StackCache.

 * plus one scheduled event. Deactivation already clears both, and WordPress
 * deactivates before deleting, so this is belt and braces for the ordinary
 * case. It earns its place on multisite: a network deactivation fires the
 * deactivation hook once, not once per site, so a per-site queue option can
 * survive it. Here every site is visited explicitly.
 *
 * Nothing StackCache owns is touched. Its settings are its own.
