Promote vPOD to a top-level project (Console/vPOD -> vPOD/)

vPOD has outgrown its home inside the console's folder: it now emulates both
halves of a pod (Munga game client + TeslaLauncher service / provisioning),
so it lives at the repo root beside Console/, Launcher/, Contract/ and
SecureConfig/, like the peer it has become.

Accompanying changes: project references rebased (Contract, SecureConfig,
the console's vendored Munga Net.dll), solution + DiffTests reference paths,
the console csproj's now-obsolete vPOD source exclusion removed, and the
root README / Apps.xml / vPOD README path mentions updated. pack.ps1 is
self-relative and now emits vPOD/dist/vPOD.zip.
