Update to reflect changes since jQuery 1.5

[addyosmani]

There have been a number of changes to jQuery since the current version of jQuery Fundamentals was written and I think that we need to try composing a list of these changes so we're as up to date as possible.

Off the top of my head, the areas that need to be addressed are:

Deferreds (see issue #3 - Eric has given us permission to use his blog post for this). I believe Dan also wrote some interesting animation pieces related to it that might be useful to absorb.

Subclassing (not really subclassing..but .sub(). I remember doing a screencast about this, but can write something if needed).

props/attributes changes - does jQF mention attribute usage where prop should be used instead? Do we want to write something up about how these should be used given a lot of people still confuse them on the bug tracker? If so, this is by far the best thread on this topic that I've found and I'd be interested in expanding one of the better answers into a page http://stackoverflow.com/questions/5874652/prop-vs-attr

Callbacks (1.7 - depends on when we aim to release. If needed use my post)

(I'll update the rest of this list as I remember what's changed. Going back through the blog posts atm).

@addyosmani can you break this up into separate issues?

[addyosmani]

@ajpiano absolutely! I'll flesh these out a little too.

We should break this into separate issues as well. Deferreds is already being tracked, jQuery.sub is deprecated and we shouldn't talk about it. Attr vs prop and $.Callbacks would be good to have content on, however.

Wow. March. Agreed - let's break this up. I have content on Callbacks etc
which you're all free to use if it helps.

[ajpiano]

Can you file a PR? I think the code org chapter would be a good place for it. Thanks!

Closing as this is way too broad. There's tons of content that should be added, "everything since 1.5" isn't nearly granular enough.
