Fixes a couple of bookmark bar bugs:

. The folders on the bookmark bar now fade in like urls.
. You can now middle click on folders to open all URLs.
. If you attempt to open a folder with more than 15 urls we'll prompt
  before openning.

BUG=242 529 1295385
TEST=middle click on a folder on the bookmark bar and make sure it
  opens all tabs in the background. Try this with a folder containing
  more than 15 bookmarks and make sure you get a message box before
  asking if you really want to open them all.
