[Flashable T-Mobile wifi calling][Sense 4+ and Sense 5]

I finally got wifi calling extracted, ported and flashable. Currently for "stock" custom Sense 4+ ROMs and Sense 5 as well.

Haven't tried trickdroid or viper, but i'll get a version for viper posted soon.

Make a nandroid first, then flash the appropriate zip in recovery. Let me know if there are any issues.
