Numerous Corrections to Hop Counts

These changes make a dramatic difference in my ability to scan all of my link tables with the fewest errors.  I have also noticed that even regular day to day operations are must more efficient. 

The changes basically:
- enable a 0 hop count
- increase send timeouts for peek related messages
- ads a brief 50 millisecond pause after receiving a message before sending a new one

I have not included any code for programatically resetting the hop counts for devices.  I do this manually with user code right now.  I agree with Michael that some sort of running average might be a solution, but I haven't out an implementation of this that makes sense yet.  In the mean time I am just resetting my hop count at 4am to 0, this seems to work.

Merging these changes shouldn't be held up while waiting for a solution to resetting the hop count.
