expand basebuglistfilter.py datereported functionality

I agree, it would be nice to have such functionality, however I doubt we cannot implement this for the most date-attributes.
The datereported filter is depending on the ability of lp to sort buglists by "newest/oldest first", this makes this filter so *fast*. As lp can return us buglists ordered by "most/least recently changed" we can easily adopt the functionality of the datereported filter for date_updated.

For all other date related attributes the workflow should look like:
1.) getting the whole list,
2.) filtering the list
I think this should be implemented in the script which needs this functionallity and not in py-lp-bugs. Please see the attached example.

So IMHO, won't fix for most date attributes. I will work on a fix for date_updated.

patch against .main rev 147 to add a dateupdated filter function to py-lp-bugs.
Needs some review and testing!

I've added a modified version of dateconfirmed_filter.py, and a similar datetriaged_filter.py, to the examples directory of python-launchpad-bugs. Thanks!

It seems to work well enough but I'm not certain what the use case for it would be, it seems to me that date_updated isn't particularly useful in bugnumbers unless it is compared with another date. For example, it'd be neat to find bugs where date-updated > date-incomplete but this isn't possible.

It's still worth adding though.

I've pushed this in revision 151.
