Title: Make accordions 'tabbable'

use closest() and find() instead of parents() and siblings() to
allow for more flexibility in markup
Set animating=true right before slideDown()
avoids having to set animating=false on focus event returning false

The only 'iffy' thing is this:
items.find(pg.settings.selectors.header).wrapInner('').children('a')
