Maintain sort upon packet signature

[adamhb123]

After signing a packet, the entire page is refreshed and any sorting you had chosen (i.e. by signature count) is undone. Not doing that would be pretty cash money.

Hmm, how are you thinking you might handle this?

I might not personally work on it for a few weeks or so. Pretty backlogged on other stuff (documenting nuinfosys, adding an api to it, getting it ready to be published publicly, etc). It could be fed to the template already sorted or could be just sorted within the template using Jinja2's sort function, but then we would need to pass a variable to the template describing how the list should be sorted, which pretty much defeats the purpose. I haven't even looked at the code so I have no firm suggestions as of right now.

My knee-jerk reaction was that it probably wouldn't be that hard so I labelled it as a good first issue. If you don't think so feel free to remove it of course.
