- Added support for loading all plugins of one type using wildcard "*". - Unloading no longer removes the plugin object. Now the member "loaded" is set to 0 and the type of a device plugin is reset. - Added plugin_cleanup() function to remove plugin objects on Bochs exit. - Some other related cleanups in the plugins code.
