Subject: [PATCH] Added support for the Beamer environments "overlayarea" and
 "overprint" in the form of environment triggers. Also added trigger support
 for the Beamer commands "onslide", "visible", "uncover" and "alert". See
 Support/latex.config for details.

Also modified the "Insert item" command to have a default behavior for overlayarea and overprint environments.
