This update includes a few important changes and bugfixes:

- The plugin now uses a separate plugin to handle head loading, called HeadsPlugin. This is done so that a new plugin doesn't have to rewrite the head loading code.
- The plugin now supports head caching. If the heads are cached, the plugin still works fine if the heads website is down during a server start.
- Fixed bug where a board reset was undone after a server restart


*Note:* both HeadsPlugin and HeadSweeper need to be put into the plugin folder
