Qt: Add idle dissection.

Features such as sorting and scroll bar colorization require
fully-dissected packets. We currently do dissection at the wrong time --
*after* the user clicks on a packet list column header or moves the
scrollbar.

Add a timer + slot that dissects packets when the UI is idle so that our
packets are at least partially dissected when we need them.
