#JC-1827 - Tooltips positions are automatically calculated.
Now the data-placement attribute now is not counted - we just calculate the best position based on the tooltip size and target DOM element position and size. First we try to place the tooltip on the top, then on the bottom, then of the right and then - we just have no choice - we place the tooltip on the left.
#JC-1827 - Tooltips positions are automatically calculated except the tooltips for which they are explicitly specified.
Now there is no default tooltip position. Position can be explicitly specified or otherwise it will be calculated automatically.
