List of livestamps contains duplicates

[lostincomputer]

Element is added to the $livestamps variable twice when I initialize livestamp twice

Code to reproduce the problem: $('#birth').livestamp(new Date('June 18, 1987')); $('#birth').livestamp(new Date('Febuary 18, 1987')); //change the date

$livestamps variable now contains the #birth element twice

@mattbradley this one is also important for memory

Another good find. This would be fixed by #11, but that pull isn't mergeable anymore. I'll fix this in v2.0.
