Logging the raw scores if enabled

If a flag is set, it'll log the phrases and internal stats to a file and
popup an email dialog.  I'm using it as input for machine learning to

as a configChange you handle in addition to orientation on API 13+
(3.2+).  Probably because the navigation buttons could be software
buttons and they move on rotate so the dimensions change.
