Modified ready to event to pass jQuery object, allowing users to avoid the ugly custom alias pattern, added examples to both ready(Function) and $(Function)

Lots of improvements. Added support for .not( jQuery("...") ) and support for multi filters: .filter("foo,bar") .parent("div, .class"), etc.

Added tests for almost everything in jquery/jquery.js; fixed some docs and removed the now useless docs for $(jQuery)

Removed duplicated show/hide/toggle, added test for toggle(), started documentation of event properties/methods

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.
