<li>New <tt>bbs.mods</tt> object for a common global repository for 3rd party modifications/modules
<li>Reduced memory usage (using the undocumented JSPROP_SHARED attribute for properties)
<li><tt>MsgBase.save_msg()</tt> will accept any variable type for the body text<br>
and will automatically convert to a string (even arrays of objects)

The following are now equivalanet in ulist (menus) and string input:<ul>
<li>^B = home

<li>^Z = help (F1)
</ul>

<li>+ = insert
<li>- = delete
<li>backspace = escape (not new)
<li>^U = pgup
<li>^D = pgdn
