Remove whitespace tag preference

Browse Source 
The vast majority of users will never uncheck this option. Those who
would can send an unencrypted untagged message through the system sms
app. It would then be stored locally in the clear, but it was already
transmitted in the clear and likely stored on the recipient's side in
the clear, so the security gains of locally encrypting are low, and
again, this seems an extremely rare edge case.

By android design pattern specs for the settings menu, we should kill
this preference.
