ui-slider: Allow cursor to be changed while dragging slider

[making718]

Users should be able to change the cursor when dragging a handle, but they currently cannot because the following line sets an inline style.

.wrap('<a href="javascript:void(0)" style="cursor:default;"></a>')

Which could be changed to something like the following to allow the style of the cursor to be changed.

.wrap('<a href="javascript:void(0)" class="ui-slider-handle-anchor"></a>')
