Default [Q] Trying to port Voice+

Hello all,

I am trying to get voice+ working, and I am almost there I believe. Cherry-picking from gerrit gives build errors, so I put the changes in by hand, and made a few more changes I found in the cm11.0 branch for SMS middleware, and got it to build. At first, if I installed the voice+ apk, I was getting permission unavailable: INTERCEPT_SMS, but now i get CANCEL_NOTIFICATIONS. The only reference to that permission I have seen anywhere is in the babel apk, so I'm wondering if it is necessary anymore in 4.4. anyone have any insight?
