Subject: move variables to tighter scope
X-Git-Url: http://challenge-bot.com/repos/?p=challenge-bot;a=commitdiff_plain;h=4fb38d0258fc0574273cdcf1000cf2820e3297f6

move variables to tighter scope

* also get rid of unused variables {forward,stop}_speed
* make desired ping times local to loop, that's the only place they're used
