Upgraded to a new javascript. The old version was not working properly in some of the new browsers (folders could not be opened or closed), and was slow to start up in some browsers.
- Fix bugs 1491, 1653 (on PG at least) - Defaults all folders to the closed state - Fix to allow un-registered users to open/close folders - Makes session_id negative when used interchangeably with user_id so it does not collide with user_id - The number of days to retain open/closed folder status is now a variable (increased default from 1 to 31 days)
