Finished modifying ATK/AT-SPI mappings based on last call comments.

In Dec 2013, we delayed making these changes until the 1.1 time frame:
- comment 430: for article role, changed to ROLE_ARTICLE from ROLE_DOCUMENT_FRAME
- comment 432/439: for menuitem role, removed aria-checked since menuitems do not support aria-checked.  For checkbox, menuitemcheckbox, menuitemradio, aria-checked states, and generally changed to "<code>STATE_CHECKABLE</code>" from "object attribute <code>checkable:true</code>".

Added "localBiblio" property to the "respecConfig" object for the correct ATK reference.
