Subject: [PATCH] uses-permission fields as Apk instance vars

This adds support for the index fields: uses-permission and
uses-permission-sdk-23.  For most index fields, Jackson handles directly
mapping the incoming data to the instance vars based on the matching
field/var names.  For uses-permission*, methods are declared for
handling those properties in the incoming index.

These fields will be ignored when using the v0 index.xml format.
