Added in RsItem a new virtual method queueType() that returns the type of the queue to

use for handling the packet: RsItem::DATA_QUEUE for data and RsItem::CONTROL_QUEUE for 
control packets, to be used in pqistreamer.

Up to now, File data chunks where the only packets that were going into the --less prioritized--
data queue. Now, the default in RsItem::queueType() being to return CONTROL_QUEUE, developpers can
choose which queue t use by simply overloading this method so that it returns a different value.

The first use of this was to make generic turtle tunnel packets use the data queue instead of 
the control queuem, which restores a correct balance between turtle downloads and friends downloads.
