Make <selectlist>'s button toggle the listbox

This patch makes the selectlist button click handler close the listbox
when it is open instead of just keeping it open or reopening it.

This patch also broke some behavior of the soon to be removed behavior
attribute which broke a bunch of tests, so I migrated some stuff from
behavior=button to type=selectlist, which I will have to do eventually
anyway.
