Provide a "noreorder" argument

[ilias@…]

from TracNav: "Since r3088, TracNav knows the nocollapse argument, which prevents the TOC from being sorted or collapsed."

If would be of benefit to have a separate "noreorder" argument.

This way a user can only disable the menu from beeing reordered, thus a clicked section is not move at the top of the menu.

a workaround seems to be, to place a top root node (e.g. simple text "Navigation" like this:+

 *  Navigation 
  * [wiki:WikiStart Home ]
  
  * [wiki:Product Product]
   * [wiki:Product Global]
   * Basic
    * [wiki:Lang]
    * [wiki:Persist]
  * [wiki:Integration Integration]
    * [wiki:Integration Global]
    * [wiki:Stack]

if you click the sub-menu "integration", it will stay at it's position instead of beeing moved up.

if you remove the "Navigation" top entry, then "Integration" will be moved up when clicked.

The noreorder option was added in r3245.
