Scope 'document' locally (also useful for sandboxing). Patch from Andrea Giammarchi. Fixes bug #4905.

We only support wrapping the first element around an element (all others are ignored). Fixes ticket #4903.

Fixed wrapping of elements that hold text nodes. Thanks to David Flanagan for the patch. Fixes #4902.

Fixed the handling of .status == 304 in Opera (it always returns 0). Also silently "pass" in Opera 9.6 (which is unable to send the correct headers with setRequestHeader). Follow-up to bug #4764.

fix for #3533, triggering an event with a colon in the name on a table no longer throws an error in IE

Adding support for etags in $.ajax() - and simplified the if-modified-since implementation. Thanks to Lawrence for the patch! Closes ticket #4764.

jquery core: removed the version.txt newline; please keep it that way, otherwise that ant replacement fails, it inserts the file content wherever it finds @VERSION

Switched to using new Function instead of eval for handling JSON parsing (Fixes bug #4680). Added support for JSON.parse, if it exists (Fixes bug #4429).

Did some light reordering of the jQuery definition. Moved window and undefined to exist in intro/outro.

fix remove and empty to work properly in IE when an element with the id of length exists. fixes ajax event hanlders in test suite from firing multiple times because they did not get cleaned up.
