[Bug_Fix] shortcut to directory in .link files caused crash

Browse source 
since the plugin browser is now closed when running plugins
rb->set_current_file() had no valid browser context and used 'random' memory
instead

also adds a way to discard levels so we can load the desired directory
instead of returning to the previous
