New forum.ssjs library for ecWeb v3.

Get guest user, ecWeb root directory, appendURL hack from modopts.ini.
(web.ini settings still read for ecWeb v2, but will be removed later.)

minor fixes - verify number arguments, remove width argument from *Section() methods, add sectionHeight property.

Index threads by starting message number (should preserve thread IDs a bit longer as older messages are deleted.)

Only cycle on getcmd() if there is no parent frame (otherwise parent frame must be cycled for updates to be drawn.)

Mark email as read when viewed, show unread email in alternate colour (like messages.)
Cosmetic changes.
Allow flat and threaded views to be shown in ascending or descending date order.

remove debug logging.

self-normalizing, self-range finding, self-profiling, self-impregnating

(Need to get this working with email afterward, if possible - MSG_READ attribute?)
Update scan pointers when a newer message is read.

var i = tree.addItem(....); i.attr = <attr>;

User #1 can delete messages.
Addressee can delete email.

add deleteItem(index) method
remove some "unintentional features"

increase speed by over 9000
ludicrous.

Includes a lightbar/hotkey message area selector.
