show_timeouts, new default

add a referance to the show_timeout var in the master config file.
change the default to enabled. !! this should not be merged yet untill some comments.

I feel this should be the default because I for one found this confusing when I first started using salt
test.ping... dont return fails... :(

when running highstate on a cluster of systems that need to work togeather, I must ensure all the selected minions are responding to the request....
