"recent" icons set

[Frédéric Mangeant <frederic.mangeant (at) steria.com>]

Hi Henrik

I'd like you to comment on a modification I made to bbgen, relative to the
"recent" gifs set.
By default, when using with "--recentgifs", a different icon is used if a
page color is less than 24 hours old.

I've modified loaddata.c to use the "recent" gifs set if a page color is
less than 1 hour old; the modification is attached.

Perhaps it would even be possible to include a new option :
- "--recentgifs=1-day" to keep the current behavior
- "--recentgifs=1-hour"
- etc.

Many thanks in advance.

Regards,
