It would be nice if that tech will be written in Python FOCS already. It doesn't have effects so could be simple.

Oh, I'm not yet implemented `ShipHull` token for unlock.

I've added support for it in #3983.

@MichaelCourtney I've merged it, token for unlock is `UnlockShipHull`.

It's fine now.

Test doesn't enforce values here by default.

Somehow it doesn't find tests.

It looks like for each test binary dependencies should be copied same way as they copied for `freeorion` target.

Looks like I need to do something with `// search bundle_path for a directory named "FreeOrion.app", exiting if not found, else constructing a path to application bundle contents` in `util/Directories.cpp`...
