jQuery bind and unbind are now deprecated

[energynumbers]

As jQuery bind and unbind are now deprecated, I suggest replacing them with on and off respectively.

This will work for all jQuery versions 1.7 to 3.0+ , will remove the warnings from jquery-migrate-3, and will help to future-proof tablesorter.

Hi @energynumbers!

Yes, I am aware of the deprecation. I wanted to maintain the compatibility of this fork with the original as much as possible, so that's why I've kept the jQuery requirement at v1.2.6, or at least tried to do that.

I'm going out of town for a month starting next week. Once I get back, I plan to dedicate more time into the Abelt project (renamed from Tablesorter v3.0) where pretty much the whole thing will be rewritten from scratch and in pure javascript. I think I'll even end up rewriting the code that already exists as I plan to use ES6.

Any progress here?
