Allow for custom classes on tooltips

[mkielar]

When I define a tooltip on an element like this:

<td data-tooltip-placement="right" 
    data-tooltip="Tooltip text..." 
    data-tooltip-append-to-body="true">...</td>

there is no way of specifying a custom css class for the tooltip. I have a need of having different tooltips with different colors, and it seems impossible now with ui-bootstrap. Something like data-tooltip-class would help a lot.

Ekhem, forgive me asking, but, a duplicate of what? I've reviewed the open and closed issues, and only found these:

• Custom css class for tooltip #1976 (closed as a duplicate)
• Tooltip styling  #2531 (closed but does not fix the issue)

I believe it was closed as a duplicate of this issue: #3126 Before opening an issue, it's best to do a search for an existing issue and commenting on that.
