Release version 0.1.12b

fixed some cases in which the autorouter was incorrectly unable to route a trace
after the autorouter completes a trace, a clean-up function tries to eliminate some of the unnecessary zig-zags
the connection currently being traced is now highlighted
there's a 'stop this trace' button (next to the cancel autoroute button). if the autorouter gets stuck for too long on a particular trace (or you can see from the highlight that the trace would be blocked), clicking 'stop this trace' turns the current trace into a jumper wire, and the autorouter goes on to the next trace.
