Added tests for comma-separated expressions in filter, not, parent, parents, siblings, prev and next.

Added support for (basic) nested parens and (basic) nested brackets. You can now do: div:not(.foo[a:not(.even)]) or div[p[a.even]].

Fixed a bug in the jQuery.prop() addition and fixed the test cases to represent the current set of features.

I broke out the ${...} functionality into a separate plugin so that we can develop it further. I left a hook in jquery.js so that this can be done, plus I left in the function() functionality.

Fixed a bug with $("body") in dynamic documents, refactored $(...), stopped the test suite from trying to run Ajax tests locally.

Fixed problem with $("div",$("body")) breaking (returning an array, of length one, containing undefined).

Reorganized the different effects to be in fx.js, instead of jquery.js - and cleaned up some of the documentation.

Updated param method to encode name as well as value (per spec:  http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4.1)

Converted instances of new function(){ ... } to use jQuery.each(...) instead. Also, removed unnecessary documentation for trigger functions (.mouseup()!?).

fixed typo (easeout); added check if jQuery._$ even exists, added examples for usage of $.noConflict()

Added in the new .noConflict() function for resolving conflict between jQuery and other $ functions.

Changed transitions to easing. easing is now an object that can be extended to add new easing functions.

Improved a lot of docs, adding description to examples, merging methods with optional arguments; Modified filter(Function) to set correct scope (this == element) instead of passing element as argument
