logging: added a log on panic

Since panics still regularly "destroy" the terminal, it is hard to get a
stack trace for panics you do not anticipate. This commit adds a panic
handler that automatically creates a logfile inside the current working
directory.

It has to be added to every goroutine that is started and will repair
the terminal on a panic.
