Subject: changing how plugins gain/lose focus.

Previously we were keeping our own state in the UI thread to
determine when to send events to the plugin. This change removes
that logic and uses the document focus to determine when events
are to be sent. This also fixes problems with the plugins
occasionally not receiving lose focus events.
