Linus Torvalds 0cf4104dc6 Handle negative dates (before the epoch) better
The Qt model sorting for the dive date was using a unsigned number,
which doesn't work for dates before 1970.

Also, the dive date parsing got the year 1900 wrong.  Not that we really
care, because other parts of date handling will screw up with any date
before the year 1904.  So if you claim to be diving before 1904, you get
basically random behavior.
