Correct implementation of TbNavbar.brandUrl, when it is empty or false
Currently, there is no way of navbar brand not being a link. Even if you set brandUrl to an empty string or false, it still renders it as a link to current page. This definatelly should render just a pure text (not a link), if brandUrl is empty of falsed.
It is quite easy to achieve this functionallity in pure Twitter Bootstrap, but there seems to be no way to get in in Yii-Bootstrap.
