feat(fls): a project's own applications through the editor model

The model carries the captured beans of a project's own applications
(ownApplicationsByNodeId); the export writes them again on the system
software of their node, and their classes go with the archive's other
entries. Checked by Java: from the exported files FILIUS loads
Accumulator and Broadcast as from the original; the export test no longer
leaves own applications out, and a probe that drops them is caught.
