people-by-hour and tags-by-hour reports limited to 7 days

If i bump them up to have more days worth of data i start hitting the `Request-URI Too Large" errors.

Options:

1. make some server side thing that i can post to, ingests the post data, then outputs the appropriate html to render
2. just generate the html locally and have Fenestro load it.

I like the 2nd option better because it removes the need for any network / server access and worrying about the reliability of that. I don't like it because it restricts this to working on the mac but honestly, I'm not going to be testing it on anything else, and i hear at least one linux distro is having issues with building the chicken... so it ain't working anywhere else anyway.
