[storages] fix fs_importing side-effect on entity.data
When creating a new File object, if fs_importing is set,
we want entity.data to be the file content instead of the
filepath for the rest of the transaction.
(see test_bfss_fs_importing_transparency) for test implementation
To make this possible, the storage hooks (entity_added / entity_updated)
must return the correct value to set in the entity dict.

$('<div id="tooltip">' + contents + '</div>').css( {
position: 'absolute',
display: 'none',
top: y + 5,
left: x + 5,
border: '1px solid #fdd',
padding: '2px',
'background-color': '#fee',
opacity: 0.80
}).appendTo("body").fadeIn(200);

function onPlotHover(event, pos, item) {

previousPoint = item.datapoint;
$("#tooltip").remove();
var x = item.datapoint[0].toFixed(2),
y = item.datapoint[1].toFixed(2);
if (item.datapoint.length == 3) {
x = new Date(item.datapoint[2]);
x = x.toLocaleDateString() + ' ' + x.toLocaleTimeString();

x = new Date(item.datapoint[2]);
x = x.strftime(item.datapoint[3]);

item.series.label + ': (' + x + ' ; ' + y + ')');
