Made several improvements for handling timestamps.  All of the .mag
files generated now get a timestamp that is derived from the date of
the last open_pdks commit.  In particular, the abstract and full views
of cells both have the same timestamp, so changing views by dereferencing
won't result in timestamp updates.  This is not as good as implementing a
checksum method, but it is an improvement over having all timestamps
being the time at which each individual file was written.
