Orca Screen Reader App Updated for GNOME 3.22 with More LibreOffice Improvements

The list of changes implemented in Orca 3.22 continues with handling for GtkListBox items in the LibreOffice office suite, workaround for various LibreOffice bugs that made Orca present wrong things, along with better handling of paragraphs in read-only documents. For the Terminal, Orca 3.22 updates some cached information, reduces chattiness by attempting to filter out terminal pager text-change noise, no longer ignores deletion events that result from the BackSpace key, add various workarounds for better VTE support, and presents terminal paste events the same way it does for other apps.
