Latest bootstrap/fuelux breaks tooltips on mbean tree.

[mk23]

Hovering over items in the mbeans tree navigation produces this error:

[Error] Error: tooltip `template` option must consist of exactly 1 top-level element!
    tip (bootstrap.js:1677:104)
    enter (bootstrap.js:1371)
    proxy (jquery.js:529)
    handle (jquery.js:5640)
    dispatch (jquery.js:5226)
    handle (jquery.js:4878)

Cause: the tree element expects a data-template="treeitem" attribute on the same node as the target of the tooltip. Bootstrap now also wants to use the data-template to store the html for the tooltip. The two clash, but can be worked around by changing fuelux to use something like data-fu-template.
