Change Crate.Lifetime from 'seconds' to ticks

As far as I could tell, this was the last place that still
used 'seconds' instead of ticks, apart from
some sound notification intervals (which are better
converted to real [milli]seconds).

Also renamed ScaredyCat.PanicLength to PanicDuration for
consistency and easier finding.
