Changes to Contention code to cover Timeslot changes

Browse Source 
Hi Cort..
The contention code didn't seem to be working. Especially when the destination timeslot was different to the source.
The contention code was using _slot when refering to the target where I  think it should be using rule['DST_TS'] 
This version works better and group hangtime seems to work.
...Colin.
