Normalize YUI config for tests. filter from url. Use the query string filter={raw|debug} to override min default filter applied to YUI config.

Moved test suites into modules for arraylist, event-synthetic, console, console-filters, async-queue, slider, stylesheet, and json. Consolidated testing in sandbox/unittest/all.html. Individual test pages still in src/(component)/tests/(component).html. More work to be done on the testing infrastructure, including addressing requisite markup or styles, possibly incorporating performance testing, isolating test env for each test suite, and possibly abstracting out YUI Test API in favor of meta-only structures translated into Y.Test.Suite/Cases
