Clean up date handling,

as a first step to get rid of the frequent petty warnings in this area:
 - always store dates as strings, not as seconds since the Epoch
 - for input, try the three most common formats everywhere
 - for unrecognized format, just pass the date though verbatim
 - when there is no date at all, still use the current date
Originally triggered by a one-line patch from Tim van der Molen,
<tbvdm at xs4all dot nl>, which is included here.
Feedback and OK on manual parts from jmc@.
