add ability to obtain hyperlink specialization

* src/orca/atspi.py: add ability to obtain hyperlink specialization

* src/orca/atspi.py: add fallback mechanism to determine string for role
for LINK and INPUT_METHOD_WINDOW - these strings somehow didn't make it
into the atk implementation (bug filed as
http://bugzilla.gnome.org/show_bug.cgi?id=361757).

* src/orca/atspi.py, src/orca/rolenames.py: add LINK, HEADING,
INPUT_METHOD_WINDOW, ENTRY, and DOCUMENT_FRAME roles that were recently
added to the AT-SPI infrastructure.
