Allow Table headers to sort ascending and descending

[lgroschen]

Allow Table headers to sort ascending and descending and preserve the sort between page loads so the user can always keep their preference. Also allowing multiple sorts to stack on each other and also save.

Then create a fallback default sort of the newest traps first and oldest last.

Going to go with some kind of jquery plugin, or something like this: https://datatables.net/examples/plug-ins/api.html

Will use bootstrap to draw the tables and buttons so not much visually should change, besides making the tables a lot more clean.

This should be rather easy. Even though it's an enhancement, we'll schedule for a 3.0.3 release.
