Changes to integrate bitdht into libretroshare.

Browse Source 
Mainly re-organising tcponudp... 
	tests->test area
	network->trash (uses libbitdht classes).
	new udp interfaces (udppeer + udpstunner)

Changes include:
	* p3bitdht: added "addReceiver() call, and more debugging. 
	* p3bitdht: added DO_IDLE flag so searches are continous.
	* p3bitdht/pqiassist: matched up Assist interface.
	* fixed pqiNetListener interface.
	* rsinit/p3connmgr: setup udp init
	* tcpstream: switched to new udp receiver.
	* added "blogs" switch in libretroshare.pro (was stopping compiling ;)
	* added "bitdht" switch in libretroshare.pro
