Don't focus to the tab which is going to be removed.

This fixes #569. In the previous revision, onTabClose method tried to focus to the first child even if it was going to be closed as a member of closing tree. Then TabSelect event was unexpectedly fired, TabWindow.prototype.handleEven (defined in resource:///modules/WindowsPreviewPerTab.jsm) raised an error, and blocked all following event handlers for TabSelect event. As the result, cached tabs list were not cleared and Ctrl-Tab feature was killed.

Don't activate UI to manage tree relations for bookmarks in the "unsorted bookmarks" folder.

We often store very large number of items into the folder, however we'll never open them as a group of bookmarks via middle click on the folder. On the other hand, if there are too many sibling bookmarks, TST can freeze to initialize the list of siblings. So I decided to disable the UI for bookmarks in the "unsorted bookmarks" folder. This decision is related to the issue #398.
