Add setting in security for sms message rate alerts

If we add a preference to control "sms_outgoing_check_max_count" we can
control the message rate by writing to Settings.Secure.SMS_OUTGOING_CHECK_MAX_COUNT.

Currently this is null so it defaults to 30 sms messages in a 15 min period.
Creating and writing this preference allows us to control the sms rate interface.
We can also modify timeframe as well.

This was added to security instead of Mms since this isn't just rate limiting the
sms application.  This rate limits any application that sends texts.

This also creates a new category called Application Security.
