Subject: [htdig] JavaScript enabled search page

I have written a search page that, with the help of the magic of
JavaScript, allows users to select either how many days ago a document was
modified or documents within a set range of dates and then sets the
startday, endday, etc., values appropriately (this overcomes the inability
of a regular web page to contain two options, in this case startday, by
the same name). It also contains some other nice functionality
(automatically sets the correct number of days for the month selected,
prevents restrict and exclude options from clobbering each other, etc.).

The one disadvantage of using this page (aside from requiring JavaScript)
is that it always sets at least startday, so it will add overhead to
htsearch as it will always examine the date for each hit to make sure it
falls within the range. That could easily be overcome in the checkStartday
function by only setting values to startday, endday, etc., if they had
been changed from the default. I'm not noticing huge slowness in searches,
so I didn't bother.

Maintainers, feel free to put this into the contrib directory somewhere. I
couldn't find anything there that did this sort of thing, so my apologies
if this is a duplicate of something already out there.
