Moved creating of stage1 package list to the beginning of stage1-chroot.sh so we can get the output with --debug, added --newuse to the options for stage1, as we should always rebuild any package where the USE has changed, removed removal of portage logs from stage2-chroot.sh since it is being done by cleanup_stages, moved world removal in cleanup_stages into a check for stages 1 through 3, made update_env_settings check for the existence of env-update before running it since we now run update_env_settings by default everywhere chroot-functions.sh is sourced, and added a section to show_debug to list the packages, since we don't yet force-enable verbose with debug.
