Just added support for Accept headers in Ajax requests - defaults to the correct header depending on the type of request that's being performmed. (Bug #1986)

Fixed an edge case in show() where the css says the display should be none.  In that case force 'block' so it will actually show.

Removed check to prevent event from being fixed twice. Unfortunately, in IE this is sometimes necessary with its global event object. Binding both a mousedown and mousemove event is an example.

Fixed a couple problems found in the test suite.  First, IE doesn't like it when text nodes were trying to duplicate their events in clone, so don't do text nodes (that shouldn't have events anyway).  Also the fx module was freezing from a recent update that wasn't quite finished.

Removed a unit test that tested to see if queued objects were of a certain type.  It was decided you can queue anything and it is up to the coder to make sure it was intended.

Fixed #2080 by removing the check for nodeType != 1.  It was put in to limit the queuing to just dom objects (ie not text nodes and comment nodes), but the queuing functionality is being used more broadly than I realized so the check is now removed.

Fixed #2027 - make sure that cloned elements (within appendTo, etc.) have their events cloned by default.

Fixed a problem in the unit tests for IE where an optimization made the test case not work.  The optimization was fine.  It was the unit test that was taking a short cut which caused it to fail after the optimization went in.

added version to all builds; changed current version to 1.2.2-pre - to be updated after each release so its clear that a build is from which milestone; build.xml cleanup (removing uselss lite, docs, test and _with_plguins targets); deleted useless docs build files (replaced by wiki and wiki xml exporter and api browsers) 

Second part of the fix for #2071.  An empty string "" was being sent to .bind() and when the events were being cleared it went in to an infinite recursive loop till memory was out.  The test was !types in the function and changing it to types == undefined fixed the error.

Changed CRLF end of lines to just LF.  Other than that there were no changes in this commit.  Try svn diff -x --ignore-eol-style -r 4224:4225 to see that.
