Add new console_reset script to bulk reset all of the tip lines on
plastic. Useful for when plastic reboots, although it needs to be run from paper of course. We should probably set up some kind of reboot utility for when plastic reboots, since when capture fires up, the "acl" files are all in the wrong group/mode. On the other hand, this shared file based permission scheme is going to end up changing anyway soon, since it won't work when the serial lines are on other machines. Will need a tip permserver at that point.
