Summary: use flash.utils.Timer for LzTimeKernel

Details:
Changed LzTimeKernelClass#setTimeout, #setInterval, #clearTimeout, 
#clearInterval to use flash.utils.Timer instead of the functions defined 
in flash.utils.*
It was necessary to change the implementation because the setTimeout 
etc. functions apparently create memory leaks within the flash player.
I created a subclass of flash.utils.Timer so that we can easily identify 
each instance (timerID property) and to support functions callbacks 
instead the event based mechanism (closure and arguments property). To 
reduce the overall number of LzKernelTimer instances up to MAX_POOL 
(currently set to 10) are cached.


Tests:
testcase from bugreport, note that cpu usage stays low
