[guardian-dev] PGP supported in Android Email app

This is SecEmail_j from a Samsung S4 that occupies the
"com.android.email" namespace on S4's. I pulled out of of an S4 Stock
ROM image from XDA so take it for what it is. It does have version 4.2
in the manifest which matches what @micahflee was saying. If someone
has an S4, or an S5 for that matter, they might want to compare but
that's as legit as I can get my hands on at the moment. I haven't
looked through it other than notice there are a lot of classes that
start with PGP.
