Unmaintained Shared IP Date Range patch 1.0.1

I actually commissioned this from Xon and it's exactly what I needed. I found the hard coded 14 day limit on the Shared IP tool to be all but useless. We have 90k+ users and 15 million posts and routinely have long perma-banned people trying to sneak under the radar, so 14 days doesn't come close to cutting it.
