Moved the basic simulation networks in their own folder
The client does no longer try to relay a packet after detected loop

This can easily lead to new detected loops if the chosen next hop has
seen the packet before
The OMNeTARA client displays a bubble in the GUI every time a route discovery times out
Moved all of the basic simulations into the right folder and cleaned up the omnetpp.ini
Fixed small leak in the OMNeTClock
Removed another memory leak caused by unecessary packet clones.
