HTML export Javascript regular expression and y2k fixes

[Jake Maciejewski]

See attached patch.

The regular expressions for date matching have nested parenthesis that
don't work as intended with 4-digit years. In sort_yymmdd, for example,
mtch[2] ends up being the first 2 digits of the 4-digit year, not the
month. The month is assigned to d, and the date is disregarded in the
sort.

I also added ? marks to match 1-digit days (the month part of the
pattern already had this) since sort_yymmdd and the others have checks
for 1-digit days.

Finally, I noticed that the y2k handling code was prepending 19 on
4-digit years, so I made it conditional on the year being 2-digit.
