revlet and path

[Hugh Senior]

There are two issues here:

[1] Accessing an external file
[2] Trying to include a pw-protected stack in a revlet build

The first was initially pursued because of difficulties with the second.

The first is a valid issue in its own right, but to accomplish the second
ensure that not only are inclusions set manually BUT ALSO security options.
Auto-detect on either will cause the standalone builder to fail. Remove BOTH
auto-detections, and the revlet builds as expected.
