* cleanup & shuffle 'folders' struct (make clean!); Order and listorder are the same; follow this change in roomlist.c
* remove unused entries from wcsession
* streamline when we flush the rooms & folder cache
* remove old roomediting code
* extract SaveRoomAide(SETA), GetCurrentRoomFlags(GETR), SetCurrentRoomFlags(SETR) into their own functions, use them all over the place; use folder struct instead of local structs / var to save state between GETR & SETR
* tab_expire.html: fix policy names we show.
