/**
* XXX - 24 Jul 04
* If you add a command that needs to run from the main browser window,
* it needs to be added to browser/base/content/browser-sets.inc as well!
*
* XXX - 04/16/01
* ACK! massive command name collision problems are causing big issues
* in getting this stuff to work in the Navigator window. For sanity's
* sake, we need to rename all the commands to be of the form cmd_bm_*
* otherwise there'll continue to be problems. For now, we're just
* renaming those that affect the personal toolbar (edit operations,
* which were clashing with the textfield controller)
*
* There are also several places that need to be updated if you need
* to change a command name.
* 1) the controller...
* - in bookmarksTree.xml if the command is tree-specifc
* - in bookmarksMenu.js if the command is DOM-specific
* - in bookmarks.js otherwise
* 2) the command nodes in the overlay or xul file
* 3) the command human-readable name key in bookmarks.properties
* 4) the function 'getCommands' in bookmarks.js
