Bug: pixidou doesn't deal well with 'undo' operations

(from [e61131706bd441c698dc67a57710b4f46a9fec56]) Attempts to fix pixidou not dealing well with 'undo' operations. At least now you can recover from an undo, although an undo, undoes everything back to square one. Also updated some bad refs to old yui locaitons [#363 Bug: pixidou doesn't deal well with 'undo' operations] https://github.com/exponentcms/exponent-cms/commit/e61131706bd441c6...

I have exponent version 2.0.1 and Linux dist. Ubuntu 11.04, PHP 5.2, Apache 2.2.X, MySQL 5.1.X

I have notice, I tried to install only pixidou from its https://github.com/asvinb/pixidou and this pixidou has the same problem

Thanks for help, I am new to exponent and it is great that this community has quick support

(from [9689ee5155fb7ac53013a9b69736e1f5a0cc1ddf]) Fully fixes Pixidou Undo (if it ever really worked). Also cleans up some other odd things to make it more intuitive like removing cancel/apply buttons if you cancel resize/crop, etc...[#363 Bug: pixidou doesn't deal well with 'undo' operations ] https://github.com/exponentcms/exponent-cms/commit/9689ee5155fb7ac5...
