Say hello to Android Services

This changeset enables running a QCoreApplication from within an Android
Service. The Android Application running can now have a QtActivity or a
QtService, but having both in the same process is not supported.

This patch was based on Cory Slep's patch

[ChangeLog][Android] Qt can now be used to easily create Android Services.
