Title: Ie leak

changed empty, now it uses destroy to clean every children tree
this change need a check on destroy, because childNodes returns
textNodes
on clean i removed the _fireEvent reference breaking the circular
reference and allowing the gc to clean up the memory (tested with
sIEve-0.0.8)
set('html',...) don't leak but set('text',...) does, so added a
Element.Properties.text setter and done empty() before setting the text

I setup a test page that creates 1000 divs, added these divs to the
body and then use empty(), set('html', ...) and set('text', ...) to get
rid of them, causing a 1000 element leak,
with these changes I managed to drop the leaks from 1000 to 0.
