Merge 32441 - Change the folder presentation in the Bookmark Editor and the Bookmark All Tabs dialogs to a tree view.

Nib changes: Removed the NSBrowser and added an NSOutlineView.

BUG=26647, 26643, 26718, 27634
TEST=Bring up the bookmark editor by controlclicking in the bookmarks bar and selecting Add Page... or by selecting the Bookmark this Page... menu item found in the Bookmarks menu.  Observe that the folder presentation is now a tree view.  Select any folder and click New Folder to verify that new folders can be added.  Doubleclick on the newly created folder to change its name.  Added folders will not commit until OK is pressed, which will require that a bookmark actually be added.  Also bring up the Bookmark All Tabs dialog by controlclicking in the tab bar with more than one tab open and verify that the folder structure is shown in a tree view.
