Allow basic markup syntax in tooltips

[lrbabe]

We should allow a few markup conversion for titles used in tooltips. for exemple, this title :

title="heading :: some info | another info"

(note that the title remains understandable and valid without conversion), could be rendered as :

<div id="tooltipHelper">

<div id="tooltipTitle">

<hX>heading</hX> some info<br /> another info

</div> <div id="tooltipURL"> </div>

</div>

the only thing to do actually is to replace line 65 of iTooltip by : jQuery('#tooltipTitle').html(title.replace(/^{(.*?)::/, "<h4>$1</h4>").replace(/ \| /g, "<br />"));}

An option could be added to ignore conversion...
