check for canceled before executing callback IE 8- sometimes executes (at least) setInterval callbacks once after clearInterval has been called. This breaks the rule of "stop" means "stop". Execution of the passed callback now only occurs if a private closed-over canceled flag is false. cancel() sets the canceled flag. Lots of tests were added for Y.later as well.

Y.later works on native IE functions that do not have an apply() method [fixes #2529845].

Y.later again propagates the data param if the context is null [fixes #2529264].

Y.later doesn't create unnecessary objects [fixes #2529156].

API submodule breakdown

Made Y.later and Y.log submodules. All YUI submodules are in build/yui. Loader pulls in yui-log and dump automatically if the debug filter is specified.

Added the id from setTimeout/setInterval to the return payload from later. Added window resize event.

refactor

Added closures to prevent local variable collisions

Globally changed all references to Y.fail. Y.fail has been renamed to Y.error so that Y.fail can be used for the assertion engine.

yui reorg, updated build and organization, get and loader source moved to yui src dir
